Error: Input file contains unsupported image format
HI. I have Immich installed on Unraid, I was having server crashes using the template install, so I transfered to the Docker Compose method using the official documentation. I am on version. V1.129.0.
I have a large quantity of photos exported from Apple Photos and then imported via Immich-Go, other photos have been imported directly from the Immich IOS app.
Docker-compose and .env file are attached.
I am getting 1000's of errors in the immich-server container such as this:
[31m[Nest] 7 - [39m03/30/2025, 12:01:06 AM [31m ERROR[39m [33m[Microservices:{"id":"3aae52cd-0e08-47de-a540-3642fd7c120a"}][39m [31mUnable to run job handler (thumbnailGeneration/generate-thumbnails): Error: Input file contains unsupported image format[39m
Eventually the server locks up with high IOWAIT and I have to restart the docker service to recover.
How can I troubleshoot this issue please?15 Replies

It seems likely you have disk / data corruption
Given the corrupt input files and high IO wait
Server crashes also indicates a major issue, as this is not something a docker container is able to cause
In the log, I assume the id:xxxx references a source file. How can I find what image files are being referenced?
You can search in the database for
select a.id, a."originalPath" from assets a where a.id = '1d8f4464-9154-4bfa-858b-dba0cd72166a';Yes, the photo appears to be corrupted. I have 1000's of these corrupted files, is there anyway I can find out what the original file name was?
Is there a way I can detect these currupted files and remove them from Immich?
You should first start by taking a full backup of immich including a database dump, and everything else on the drive, and investigate why your storage is failing.
The original file names should be stored in the immich database
It can be added as
a.”originalFileName” in the sql query you haveThanks, I've found the original file name, I'm now searching for this in the original source files to see if it was corrupted prior to the import.
The files appear to be duplicates, but the files are prefixed with ._
i.e. .DSCF1805.JPG and DSCF1805.JPG
Any idea why this may be? Is there an easy way to search for files prefixed with . and delete them. (I have a database dump and full backup.)
That’s probably a small file created by your operating system — likely Mac OS
You shouldn’t have uploaded them. Might be a thumbnail or metadata
Yes, I'm on a Mac, I suspect you are correct. Can I do a wildcard search inside Immich App and just delete them all?
It would be better to start over and upload only the good files
I wouldn’t expect a search to be terribly successful
You could query the DB for a list of files then delete using the API I guess
An underscore is a wildcard character in Postgres so the search will not work as expected within immich
ok, yes starting from scratch might be the best idea. I've been using Immich for a few months, so I'll have to see if my recent photos that have been importing direct from my phone are still available.
Thanks for your help.
This search seems to work, I think I'm going to try and delete them.
I’m pretty sure that will cover a lot more files than you want, also you can’t manually delete from the DB as there will be hanging references in other tables
The search, seemed to return just those files starting with ._
But if I can't delete them without causing DB issues then I'll leave it for now.
The patten will grab anything starting with .
And no, you can’t delete with the DB
