[BUG] - Bug when input type is file.

NextUI Version

2.2.9 2.4.1

Describe the bug

When using the input component with file type, I observed that on the first click to choose a file, the selected file is logged as "undefined" in the console. However, on the second attempt, the correct file information is logged

I am experiencing the same issue. For now, I am using a regular input element and styled it the same.

This seems to be an issue since value="" is set on the input element that NextUI creates. It looks like value="" is assumed to be the default which isn't true for inputs with type=file. In use-input.ts, an empty string is always assumed to be the default value an input should be.

If I force value to be null, the file input works as expected:

<Input
    {...rest}
    // @ts-expect-error -- Known issue with NextUI's Input component
    defaultValue={null}
    multiple={allowMultiple}
    onChange={handleChange}
    type="file"
    // @ts-expect-error -- Known issue with NextUI's Input component
    value={null}
/>

Don't actually do the above in production, it does give a warning that values should not be null, they should be undefined for uncontrolled components. This is just to demonstrate that the empty string appears to be the issue.

There are some related tickets to this issue in the issue tracker:
