That error has nothing to do with the problem described. Anything else in the logs? Does the autocomplete reqeust show up in the network tab? Does it return any results?

[rollanders]

I do not understand what is "the network tab"?
Autocomplete only works for individual adresses. But not for Groups - as it used to.
I created a Group "Test". Added one user to that group. Tried to send a mail to Test and also to Test(Group). Normally autocomplete should recognise and propose the group but it does not. And when I send a message to Test or to Test(Group) I get an error.

This is a regression I saw on my side when migrating from 16.0.8 to 17.0.4.
It was working fine with NC16 and right after the upgrade it is not working anymore (I am sure as I am using a group to send mail just before upgrade starts and right after upgrade is done).

Indeed, the group are not shown anymore during the autocomplete.
I cannot also use Nextcloud user names anymore in the autocomplete.

Probably a regression between v0.17 (NC16 compatible) and current v1.1.3.

[ChristophWurst]

Probably a regression between v0.17 (NC16 compatible) and current v1.1.3.

That or a change in logic for the code that provides the suggestions. Someone has to investigate. Are you familiar with xdebug?

[doc75]

@ChristophWurst I have never used xdebug, but I am ready to try.
I installed it in the php-fpm container and added the line mentionned at the end of pecl install xdebug in a .conf file located in /usr/local/etc/php-fpm.d/` directory.

But after I do not know where to find the information from XDebug.
I'll try to learn how to use it to see if I can help on debugging this.

[ChristophWurst]

The idea is to step through the code to inspect the values. So you'll need an IDE like VSCode, Netbeans or PhpStorm. Then configure the xdebug to send debugging requests to the IDEs port.

[rollanders]

@ChristophWurst The autocomplete seems to works differently in Talk and för sharing things. Do you use different algorithms?

[ChristophWurst]

Yes, it's different because we also use contacts data and similar.

[doc75]

@ChristophWurst I finally succeeded in setting up Xdebug with Codium.

I can notice that the group integration seems to query only the Contact groups. It seems that no code is looking for the groups created by the admin in the page containing all the NC users.

I have no clue on how we can search for groups created by the admin in the user panel. Any idea on where I can find such information ?

I might be wrong as this is my first debug ever in PHP and XDebug, sorry if this is the case.

[ChristophWurst]

Nextcloud groups should be resovled by \OCA\Mail\Service\Group\NextcloudGroupService. Was that class ever contacted?

[ChristophWurst]

Found it!

I just tested this on NC18 + Mail 1.4.1 and it is working fine again. I am not sure on which version it has been solved. Good news.
