Error 422 loading a pdf to be signed

[ktrls]

Hi, after the resolution of the issue #4455 I continued to test the libresign.
I'm able to assign a signer and draw a signing area. The signer receive the mail but when I click on the link and after the login I have a NO FILE FOUND error page.

Then I click on libresign icon and I view in the list of the document, the pdf to be signed.
I try to sign it but I wait forever.
So I try to sign with the browser console opened and this is the result:

Content-Security-Policy: Le impostazioni della pagina hanno bloccato l’esecuzione di un worker script (worker-src) da https://myserver/nextcloud/apps/libresign/js/pdf.worker.min.mjs in quanto viola la seguente direttiva: “script-src 'nonce-Ckc6FXiuc6w2LLChmWUBSfDqjfn2YkcKvivdHsVU/9Q=' 'unsafe-eval'”

and as a last error

Object { message: 'Unexpected server response (422) while retrieving PDF "https://myserver/nextcloud/apps/libresign/pdf/0009430e-bda9-48ee-ba43-5abad79a097a".', name: "UnexpectedResponseException", status: 422, stack: "29082/r/4491/ue<@https:///nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:1770445\n4491@https:///nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:1770473\nn@https:///nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:2146048\n29082/r/<@https://myserver/nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:2171260\n29082/r/<@https://myserver/nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:2590086\nr@https://myserver/nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:2590091\n29082@https://myserver/nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:2590105\no@https://myserver/nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:4960483\n65111@https://myserver/nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:3668248\no@https://myserver/nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:4960483\n@https://myserver/nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:4980008\n@https://myserver/nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:5045898\n@https://myserver/nextcloud/apps/libresign/js/libresign-main.js?v=49e87620-0:2:5045902\n" }

The signer receive the mail but when I click on the link and after the login I have a NO FILE FOUND error page.

Could you provide a screenshot of this page took at the newest version?

I made changes at this page at newest version to display more details about what's happening. At the previous version the reason to display this page wasn't displayed.

[vitormattos]

"https://myserver/nextcloud/apps/libresign/pdf/0009430e-bda9-48ee-ba43-5abad79a097a".', name: "UnexpectedResponseException", status: 422

This is an issue from api side.

Could you provide the body of this request also at developer tools of your browser?

And also would be good to check if have any entry at nextcloud.log file when this request is made.

[ktrls]

In the error nextcloud logs I read

_2025/01/27 17:06:35 [error] 308778#308778: *7 FastCGI sent in stderr: "PHP message: PHP Fatal error: Trait "OCA\Libresign\Handler\CertificateEngine\OrderCertificatesTrait" not found in /var/www/nextcloud/apps/libresign/lib/Handler/CertificateEngine/AEngineHandler.php on line 49" while reading response header from upstream, client: 82.192.135.167, server: , request: "GET /nextcloud/apps/files/ HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php-fpm.sock:", host: "vmi1532086.contaboserver.net"

and nothing else.

In the access nextcloud logs I read

If I open the browser's developer tools I see this

So the response says: expired link

I don't know if is userful but in my server I use php 8.3
Let mi know if you need something else

These are the screenshot:

selecting the file to sign

after click on the "Firma" (Sign) button

[vitormattos]

Your issue is this:

OCA\Libresign\Handler\CertificateEngine\OrderCertificatesTrait" not found in /var/www/nextcloud/apps/libresign/lib/Handler/CertificateEngine/AEngineHandler.php on line 49

Are you with the newest release of LibreSign?

This error is very strange because have integration and unit tests covering this code.

[ktrls]

My versoni is 10.6.1

I try to load a video

firefox_qmlzRIPEFu.mp4

[vitormattos]

What's the body that stay at body of this endpoint with status code 422?

[ktrls]

is this the answer of your question?

Maybe there is some permission rule to make on the file system?

I check again the configuration of libresign after the update and I found some errors so I did the occ instruction to repair and now all is green.

I check again the configuration of libresign after the update and I found some errors so I did the occ instruction to repair and now all is green.

I made a update of Java version:

• chore: bump java #4530

After every dependency version upgrade, is necessary to download the newest version of outdated dependency.

The issue is the error that you found at your log file:

OCA\Libresign\Handler\CertificateEngine\OrderCertificatesTrait" not found in /var/www/nextcloud/apps/libresign/lib/Handler/CertificateEngine/AEngineHandler.php on line 49

But the problem is that I can't reproduce this and have a lot of tests covering this row at CI flow every when a PR is made and before all releases.

I made two PR that could solve your scenario:

This PR is a workaround to solve a problem at other apps like Mail at Nextcloud 31.

• hotfix: prevent call other autoload before libresign #4596

This is a problem with languages that have accents at some words of the footer that could be added at signed files.

• fix: use entities instead of char convertoing #4624

Hi Victor, thanks for your work. I tried to search in the log files but I was unlucky and have no other details to write here.

I'm happy if my problem can growing up the solution.

So I'm waiting the next update of the app to try again

[vitormattos]

Could you check again at the newest release of LibreSign?

I made a lot of improvements.

Closing this issue as solved.
