gotenberg: unoconv PDF: unix process error: wait for unix process: exit status 5

The issue is still occuring with the latest 7.7.1

I also have this issue, i cannot convert epub files. Gotenberg 7.7.0

docker run --rm -p 3000:3000 gotenberg/gotenberg
curl -X POST 'http://localhost:3042/forms/libreoffice/convert' -F 'files=@"./Alices_Adventures_in_Wonderland.epub"' -o test.pdf

Results in the error message:

{"level":"error","ts":1667908795.8060749,"logger":"api","msg":"convert to PDF: unoconv PDF: unix process error: wait for unix process: exit status 5","trace":"0f13fdf3-7067-475b-b0ca-0e2b260300aa","remote_ip":"172.17.0.1","host":"localhost:3042","uri":"/forms/libreoffice/convert","method":"POST","path":"/forms/libreoffice/convert","referer":"","user_agent":"curl/7.86.0","status":500,"latency":136665529,"latency_human":"136.665529ms","bytes_in":886127,"bytes_out":21}

I have tried many epub files, the one in this example was taken from here.

Maybe related to https://bugs.documentfoundation.org/show_bug.cgi?id=146807 / https://bugs.documentfoundation.org/show_bug.cgi?id=151766 A crash could explain why the document is Null when attempting to load via unoconv. But I can’t be sure sadly - If anyone want’s to investigate further into that, I’d be glad. Will try to research and test further with 7.7.1 - maybe with “bisecting” there are new information to be found 😕

Test in progress on my dev environment. Keep in touch!

Edit : Seems to be good. It’s quicker without --uno-listener-restart-threshold=0 and no more bug after waiting period.

Release 7.7.2 is now available with the fix. Please open a new issue if the problem still persist 😄

Deployed the update on our dev system and will monitor the behavior. I’ll keep you updated!

@PhE @cars10 @PierreSchwang @ytilotti could you try the image gulnap/gotenberg:libreofficefix? It’s using a downgraded version of LibreOffice (7.0.4) but with the Gotenberg 7.7.1 codebase.

Hi! After quick testing with multiple requests with a bit of a time difference (13:54, 14:24, 14:44) it seems to work so far. Do you know the culprit? I’ll try to test further but looks promising so far, thanks!

My feedback was without stateless mode. After new test with stateless mode (--uno-listener-restart-threshold=0) it’s working. More slow but working.

Hi @PierreSchwang, same problem here with version 7.6.1.

Process:

1. Up the instance of docker
2. Convert files with call /forms/libreoffice/convert
3. File pdf generated
4. Call /health, API up
5. Convert files with call /forms/libreoffice/convert
6. File pdf generated
7. Call /health, API up
8. Wait 10 minutes
9. Convert with call /forms/libreoffice/convert
10. Error convert to PDF: unoconv PDF: unix process error: wait for unix process: exit status 5
11. Call /health, API up
12. restart the instance
13. Convert with /forms/libreoffice/convert
14. File pdf generated

I don’t understand. Ater few minutes without activity, the error appear without PDF/A-1a.

Small status update: Seems like this is no issue with long-term runs only, but happens on freshly restarted containers after 2 hours now as well 😕

Edit - even more information: After triggering unoconv in the container manually, I can reproduce the same exit code:

gotenberg@daf006eb8a88:~$ unoconv --no-launch --format pdf --port 45379 -vvv --export SelectPdfVersion=1 --output out.pdf xxx.pdf
Verbosity set to level 3

unoconv: UnoException during import phase:

gotenberg@daf006eb8a88:~$ echo $?

Still no idea why tho
