Pending release Invalid file checksum (code 100) when uploading GIF on Docker Chevereto 4.3.7

[bbq001]

I'm running Chevereto 4.3.7 (Docker version) and encountered an issue when uploading a .gif file.
The upload process fails with the following error message on the web UI:

I have already enabled “Debug errors” in the system settings and followed the official Debug documentation, but there is no useful information or stack trace on the page.
The JSON response is :

{"status_code":500,"error":{"message":"Invalid file checksum [Code: 100]","type":"Exception","time":"2025-11-03T16:55:26+00:00","code":100,"id":"6908de7e11556"},"status_txt":"Internal Server Error"}

I also ran this command:

docker logs e5715c617656 -f 1>/dev/null

However, there are no new error logs, only old entries from last week.

Is there any way to make Chevereto or PHP output detailed error logs in Docker (e.g., to php://stderr or another file)?

GIF works for me: https://demo.chevereto.com/image/1JKX.BNQrC

Most likely your file is corrupted. Can you upload the gif as zip so we can check why that file fails?

The GIF file is quite large — about 18.2 MB, and it contains NSFW content.
Would it be appropriate to upload it here as an attachment, or should I provide an external link instead?
I’ve tested other files around 19 MB, and they upload successfully — only this specific file causes the error.
