This fails for a particular picture being imported, doesn't it? Could you share with us that picture so that we can reproduce the problem on our end?

[jhrcc]

I didn't locate the specific one, I did it through Import from Server
path, after the error message, many paths can not be imported, but the single upload method can be uploaded
Here are the names of my files

Multiple repeat imports will randomly import one or more sheets

[nagmat84]

As @kamil4 said it seems to be a specific failf (or a specific category of files) which is failing. These files have probably exhibited certain characteristics which the EXIF tool is not capable of handling (e.g. a particular EXIF attribute, etc.) . So without the specific file it will be difficult to solve this problem. The list of file names is not really helpful.

However, if you are very brave and if you have the possibility, you could try to switch to the branch "consistent_json_api". The main achievement of this branch is a consistent and much more accurate error reporting. Maybe this branch would provide you and us with an error message which helps to solve this problem.

Okay, I'll try it.

[kamil4]

It's failing here: https://github.com/LycheeOrg/php-exif/blob/2f74ba7d7a66bc8c9af4e8e8731797d9d4103437/lib/PHPExif/Mapper/Exiftool.php#L355 so it must be getting triggered by IPTC:Keywords or XMP-dc:Subject (probably both present at the same time, actually). That's where tags are stored, I believe?

[kamil4]

@jhrcc Just to make sure that I understand, did you try uploading the same set of photos using Upload Photos functionality? I would expect it should fail also, but it should make it much easier to figure out which file(s) it's failing on...

Thank you, after I imported the photos once by importing them, all the rest can be imported normally, so I closed this issue

I just hit same problem while importing photo with single keyword in both tags. Solution is to "homegenize" $value of tags.

For anyone, like me, who also hit this problem, a quick workaround is to remove the XMP-dc:Subject tag from all images before importing. I used:

find . -type f -exec exiv2 -M "del Xmp.dc.subject" \{\} \;

This also fixed it for me... if this can be called a fix at least.

Please check whether you still have problems uploading your photos with the recent version of Lychee. This mystic error message Server error or APl not found is gone for quite a while. The backend had thrown this message for any kind of error. This indicates that you are using an outdated version of Lychee. Since then, there has also been some bug fixes to the EXIF data extractor.

If the bug still exists on a up-to-date version of Lychee, please file a new issue with the updated (and proper) error message. We would also be interested into the failing sample photo.

I'm using the latest LSIO docker, which I installed last week. Should be version 4.4.0. Is that too old?

[kamil4]

Yeah, 4.4.0 is too old. This bug was fixed in 4.5.3. Note that our official docker image is at https://hub.docker.com/r/lycheeorg/lychee

Thank you for the clarification!
I guess this could be closed then?

[qwerty287]

It was closed already :)

[adrfantini]

It was closed already :)

😄
sorry, long days. Keep up the good work
