Error signature - TCPDF

[Alexis-M51]

Describe the bug
When I try to sign a document, libresign gives me an error saying that I must contact the administrator

To Reproduce

From any file click on the details (three dots at the right)
In the LibreSign tab click on "Request"
Fill the email and click in "Add"
Click on "Submit Request"
A popup ask if we want to configure visible signatures, should be a YES/NO dialog but is a OK/CANCEL dialog
Click "Yes"
I add a signature
I go to the email where the signature request was made
I click on "sign"
I type the password
Is it when validating the password that I get the error that appears

Expected behavior
The goal is to have a validation of the signature

Hi Alexis, thanks for always you send an excellent report with all steps to reproduce the scenarios.

We only have a point in code with the message "Internal error. Contact admin." and this occurs when is an unidentified error. LibreSign send the error message to Nextcloud log as you described. I reproduced your scenario and variants of him, but I couldn't reproduce the problem. I searched by function array_map in LibreSign, but we have only a place with this function and the second argument haven't $array. Searching in the entire codebase of Nextcloud I found two places when the second argument is the var $array, I reproduced the scenario, but the two rows isn't trigged.

Could you help a bit more to identify what happening?

Is here the place that send the error to log file and return the error to client:
https://github.com/LibreSign/libresign/blob/main/lib/Controller/SignFileController.php#L237-L238
Could you put the following row before the previous two rows and return here with the backtrace that will be send to Nextcloud log?
$this->logger->error(json_encode($th->getTrace()));
Maybe we can put this row in next version to identify other corner cases.

I added the line of code as requested, here is what I have in addition in the logs

Hello, I come back to the bug which is still relevant.
I'm on Nextcloud version 25.0.1 with LibreSign version 6.1.2
I add that the bug occurs even if I enter the wrong password. I don't get a message saying the password is wrong.

[Alexis-M51]

array_map(): Argument #2 ($array) must be of type array, bool given

[unnilennium]

a files with .signé is added even if the error occurs, it is a copy of the orirginal file without any signature.

[vitormattos]

@Alexis-M51 I launched a new release bumping the TCPDF package and I think that could solve this problem.

@Fr0ggys and @unnilennium We dropped the support to version 24 of Nextcloud because we have no one helping the libresign developers with funding to maintain the support to version 24. If you want to use LibreSign with the newest features and changes, upgrade your server to 25, or, if you prefer to use version 24 will be necessary talk with us to identify how much is necessary to funding the project and maintain the support to server with version 24.

Hi,
I just installed LibreSign on my NextCloud, got it successfully configured, and sent a signing request to myself for a document.

When I followed the link, it asked me to create a pw, and then confirm a pw (I used my NextCloud pw for this -- should it be different?)

And then I got this message - Error creating new password, please contact the administrator.

The logs are showing this:

[libresign] Error: Cannot set non existing property OCA\Libresign\Handler\CfsslHandler->set = array (
0 => 'United States',
).

POST /apps/libresign/api/0.1/account/signature
from x.x.x.x by john at 2023-02-16T18:45:02+00:00

... that is what I entered in cfssl:config, for country...

NextCloud 25.0.3
LibreSign 6.2.6

[sergeng]

Exactly same error

[freelock]

So the "country" setting should be the ISO 2-character country code, not the full country.

To fix this, use the "Regenerate root certificate" button on the Libresign settings page, and set this value correctly. This solved my issue...

Although for some reason this button didn't show up at first. How I actually fixed this was by finding the incorrect setting in the database oc_appconfig table, with appid = 'libresign' and configkey = 'rootCert'. Deleting that value made it so I could regenerate it in the UI.

[vitormattos]

I made a lot of changes and removed the interaction of TCPDF at this point. I created a new release of LibreSign. Could you test and check if this issue was solved?

I will close this issue as resolved.

I think that this issue is outdated and this already was solved. If you identify a behavior related to this, create a new issue with the steps to reproduce your scenario and put the #889 code to make reference to this issue.

Thanks for all by comments here.
