@greg-schroeder I haven't added the External label as I wasn't 100% sure about this issue. Please take a look and add the label if you agree it's a bug and can be handled by external contributors.

Proposal

Please re-state the problem that we are trying to solve in this issue.

We are not showing a fallback image when image loading fails.

What is the root cause of that problem?

in the Image component here and here we don't have a mechanism to display a fallback image when image loading fails.

What changes do you think we should make in order to solve the problem?

we should make usage of the onError prop of react-native Image component expo-image Image component.
https://reactnative.dev/docs/image#onerror
https://docs.expo.dev/versions/latest/sdk/image/#onerror
add a prop to our Image component to accept a fallbackSource for the fallback image.
add a new state to the component:

    const [hasImageError, setHasImageError] = useState(false);

add this function:

    const handleImageError = () => {
        setHasImageError(true);
    };

and pass it as onError prop for react-native and expo-image Image components here and here
example:

    return (
        <RNImage
            // eslint-disable-next-line react/jsx-props-no-spreading
            {...forwardedProps}
            source={hasImageError ? fallbackSource : source}
            onError={handleImageError}
        />
    );

based on the hasImageError we determine if we should use fallbackSource or source.

and then, here:

App/src/components/MoneyRequestConfirmationList.tsx

Lines 627 to 634 in 3e74ddf

	<Image
	style={styles.moneyRequestImage}
	source={{uri: receiptData?.thumbnail ?? receiptData?.image}}
	// AuthToken is required when retrieving the image from the server
	// but we don't need it to load the blob:// or file:// image when starting a money request / split bill
	// So if we have a thumbnail, it means we're retrieving the image from the server
	isAuthTokenRequired={!!receiptData.thumbnail}
	/>

we should pass fallbackSource for the receipt.

we should ask design team to design the fallback error image for the receipt.

we can also design a generic fallback error image and use it as a fallbackSource default prop value for Image component.

Result:

for demo, I used @assets/images/eReceiptBGs/eReceiptBG_pink.png image as a fallback image:

fallback.image.Recording.2024-02-29.010427.mp4

What alternative solutions did you explore? (Optional)

we can also use defaultsource prop for react-native Image component and placeholder for expo-image Image component.
https://reactnative.dev/docs/image#defaultsource
https://docs.expo.dev/versions/latest/sdk/image/#placeholder
but the placeholder image will also show when loading.

### Proposal

Please re-state the problem that we are trying to solve in this issue.

[MEDIUM] Scan - No thumbnail is shown for the corrupted file in receipt preview

What is the root cause of that problem?

We don't handle image errors in MoneyTemporaryForRefactorRequestConfirmationList & we don't check for errors before returning the thumbnail & image.

App/src/libs/ReceiptUtils.ts

Line 36 in a5092f5

function getThumbnailAndImageURIs(transaction: OnyxEntry<Transaction>, receiptPath: string | null = null, receiptFileName: string | null = null): ThumbnailAndImageURI {

What changes do you think we should make in order to solve the problem?

For showing the default svgs like ReceiptGeneric, we need to follow steps below.

1. Create a state for image error and set that to true when onError triggers on component.
2. Pass the error state to getThumbnailAndImageURIs util function.
3. Before returning thumbnail & image url check for error which is passed.
   

   App/src/libs/ReceiptUtils.ts

   Line 54 in a5092f5

   if (isReceiptImage && typeof path === 'string' && (path.startsWith('blob:') || path.startsWith('file:'))) {

   
   

   App/src/libs/ReceiptUtils.ts

   Line 58 in a5092f5

   if (isReceiptImage) {

    // For local files, we won't have a thumbnail yet
    if (isReceiptImage && !error && typeof path === 'string' && (path.startsWith('blob:') || path.startsWith('file:'))) {
        return {thumbnail: null, image: path, isLocalFile: true, filename};
    }

    if (isReceiptImage && !error) {
        return {thumbnail: `${path}.1024.jpg`, image: path, filename};
    }

Result

corruptedImageBug.mp4

Alternatively

We can directly use ReceiptGeneric image as source when image error is true.
source={{uri: imageError ? ReceiptGeneric : receiptThumbnail || receiptImage}}

Proposal

Please re-state the problem that we are trying to solve in this issue.

Android - IOU - Nothing happens when you select corrupted jpg file in SmartScan/no error message

What is the root cause of that problem?

ImageSize.getSize fails to get the size of the image when its corrupted and throws error, but we don't handle it to show alert incase it fails.

App/src/components/AttachmentPicker/index.native.js

Lines 271 to 274 in e9c112a

	RNImage.getSize(fileData.fileCopyUri || fileData.uri, (width, height) => {
	fileData.width = width;
	fileData.height = height;
	return validateAndCompleteAttachmentSelection(fileData);

What changes do you think we should make in order to solve the problem?

We need to use third parameter of ImageSize.getSize which receives a failure callback and handle the error accordingly. Incase of corrupt image it throws unknown image format, we can use it and show corrupt image alert else we will show general alert.

For no-preview files we cannot detect if corrupted or not so we will use the image suggested by design team and pass it to fallbackSource.

App/src/components/MoneyRequestConfirmationList.tsx

Line 627 in 3e74ddf

<Image

ImageSize.getSize(
   fileData.fileCopyUri || fileData.uri,
   (width, height) => {
       fileData.width = width;
       fileData.height = height;
       return validateAndCompleteAttachmentSelection(fileData);
   },
   (error) => {
       if (error.message === 'unknown image format') {
           showImageCorruptionAlert();
       } else {
           showGeneralAlert();
       }
   },
);

If we want to block users from adding corrupted images on web also we can use ImageSize.getSize and block user and show modal when failure callback is called.

            ImageSize.getSize(
               fileCopy.fileCopyUri || fileCopy.uri,
               () => {},
               (e) => {
                   /// Block users and show message.
               },
           );

This is just a pseudo-code, it will require more changes but approach will be to use RNImage.getSize to check if the image file is corrupted or not. Will only add this check for images by using Str.isImage(fileCopy.fileName || fileCopy.name)

Pseudo code for web

    function checkIfImageIsCorrupted(file) {
        return new Promise((resolve, reject) => {
            if (!Str.isImage(file.name)) {
                resolve(true)
            }
            ImageSize.getSize(file.uri)
                .then((r) => {
                    resolve(true);
                })
                .catch(() => {
                    reject(new Error(`'Error reading file: The file is corrupted`));
                });
        });
    }

    function validateReceipt(file) {
        return checkIfImageIsCorrupted(file)
            .then(() => {
                const {fileExtension} = FileUtils.splitExtensionFromFileName(lodashGet(file, 'name', ''));
                if (!CONST.API_ATTACHMENT_VALIDATIONS.ALLOWED_RECEIPT_EXTENSIONS.includes(fileExtension.toLowerCase())) {
                    setUploadReceiptError(true, 'attachmentPicker.wrongFileType', 'attachmentPicker.notAllowedExtension');
                    return false;
                }

                if (lodashGet(file, 'size', 0) > CONST.API_ATTACHMENT_VALIDATIONS.MAX_SIZE) {
                    setUploadReceiptError(true, 'attachmentPicker.attachmentTooLarge', 'attachmentPicker.sizeExceeded');
                    return false;
                }

                if (lodashGet(file, 'size', 0) < CONST.API_ATTACHMENT_VALIDATIONS.MIN_SIZE) {
                    setUploadReceiptError(true, 'attachmentPicker.attachmentTooSmall', 'attachmentPicker.sizeNotMet');
                    return false;
                }
                return true;
            })
            .catch(() => {
                setUploadReceiptError(true, 'attachmentPicker.attachmentError', 'attachmentPicker.errorWhileSelectingCorruptedImage');
                return false;
            });
    }

    const setReceiptAndNavigate = (file) => {
        validateReceipt(file).then((isFileValid) => {
            if (!isFileValid) {
                return;
            }
            // Store the receipt on the transaction object in Onyx
            const source = URL.createObjectURL(file);
            IOU.setMoneyRequestReceipt(transactionID, source, file.name, action !== CONST.IOU.ACTION.EDIT);

            if (action === CONST.IOU.ACTION.EDIT) {
                updateScanAndNavigate(file, source);
                return;
            }

            navigateToConfirmationStep();
        });
    };

Fix for native bug here: /issues/38389

RNImage.getSize(
   fileData.fileCopyUri || fileData.uri,
   (width, height) => {
       fileData.width = width;
       fileData.height = height;
       return validateAndCompleteAttachmentSelection(fileData);
   },
   (error) => {
       validateAndCompleteAttachmentSelection(fileData);
   },
);

Result

corrupt_image_fix.mp4

Alternative

Or simply use fileData (without modifications) when error callback is triggered.

RNImage.getSize(
   fileData.fileCopyUri || fileData.uri,
   (width, height) => {
       fileData.width = width;
       fileData.height = height;
       return validateAndCompleteAttachmentSelection(fileData);
   },
   (error) => {
       validateAndCompleteAttachmentSelection(fileData);
   },
);

The corrupted file used to create this issue seems to be a very small image, only 16 x 16 pixels. A thumbnail of this image might appear blank, possibly. The corrupted file I am using works as expected. I see a thumbnail of it.
