Creating CSV view fails with implode error about moodle-mod_datalynx HOT 7 CLOSED

Could you provide your PHP version? I assume it is 8.0 or 8.1. This might be related to stricter handling of type declarations. I will check that.

Thanks a lot for your swift reply. I need to check the PHP version with the server admin, I don't have admin access to this installation. I will provide this asap.

And yes, I'm assuming 8.x as well, because the legacy signature was removed from 7.4 to 8.0. This is why I checked the usage of implode within your module's code. I also added rules in order to check, if non-existing rules might cause this error, but it still happens.

The installation is based on Moodle 4.1.5 and PHP 8.1.2 (for Ubuntu).

Fixed in 332483a

Workaround: First create fields, then create the view (makes mor sense)

You can get the new version at https://moodle.org/plugins/mod_datalynx/v3.0-dataintelligence/29825

Thanks a lot for the immediate update!
I'm not sure, if the workaround will do the job. I added fields first, created tabular, grid and pdf afterwards, then CSV creation fails. We will install the fix asap and let you know, if it resolves the issue.

The issue is resolved, CSV is working as expected. Thanks a lot for your assistance!
