[BUG] 'Unable to run java; is it installed?' stops Tika server from starting correctly

[bbbart]

Description

I am running paperless-ngx 1.14.5 using the docker images pulled from the docker hub. Everything seems to work smoothly, until I just uploaded a few .docx files.

• The frontend doesn't really give me any error, it just 'hangs' after 'upload completed'.
• However, when I check the File Tasks, I see it failed with the message "Unable to start Tika server"
• Checking the docker logs from the command line gives me a bit more information:

Strangely however, docker-compse ps clearly lists /bin/sh -c 'exec java -cp \"/tika-server-standard-${TIKA_VERSION}.jar:/tika-extras/*\" org.apache.tika.server.core.TikaServerCli -h 0.0.0.0 $0 $@' as the command for the paperless-tika-1 image (ghcr.io/paperless-ngx/tika:latest), so java seems installed after all?

Steps to reproduce

1. pull the latest paperless-ngx docker image
2. run it
3. let is consume a .docx file

not relevant in this case,I think?

I have access to all logs and am happy to share if necessary.

Other

No response

If you’re using our compose http://localhost:9998/ isn’t correct, that’d be hitting port 9998 on the webserver container

In general I’m not aware of any issues with these

[stumpylog]

Yes, I agree. You haven't configured Tika correctly and the current client we use it attempting to download and run a jar file instead.

You can see an example compose file with Tika here. In particular, these lines show how to correctly configure the remote Tika image.

[bbbart]

Ah, I see. I indeed changed the domains from tika and gotenborg to localhost. Guess I was trying to be smart about it.

Anyway, after reverting these two changes, I'm now back to the error I had before I started meddling around. I'll copy paste the error below, but feel free to let me know if this requires a new issue to be opened.

Re-create the containers, this has come up a few times, https://github.com/paperless-ngx/paperless-ngx/discussions/2868 https://github.com/search?q=repo%3Apaperless-ngx%2Fpaperless-ngx+gotenberg+bad+request&type=issues https://github.com/search?q=repo%3Apaperless-ngx%2Fpaperless-ngx+gotenberg+bad+request&type=discussions and seems to be setup-related, not a real bug

[bbbart]

ah, that works. moved to gotenborg 7.8 as well.

thanks for the pointer!
