Bug in Customer Processmanagement Modul

[StefanRother-OTOBO]

When I share an activity dialog with the customer interface only, the buttons are still displayed, but the dialog itself does not appear. Instead, I get the following message in the log:

ERROR: OTOBO-CGI-59 Perl: 5.34.0 OS: linux Time: Thu Feb 10 11:22:38 2022

 Message: No follow up process configured!

Reason:

The following query is made in the Kernel/Modules/CustomerTicketProcess.pm file, , but no process is returned at this moment.

 133     # get all follow up processes
 134     my $FollowupProcessList = $ProcessObject->ProcessList(
 135         ProcessState => \@ProcessStates,
 136         Interface    => [ 'AgentInterface', 'CustomerInterface' ],

Solution:

Remove 'Interface => [ 'AgentInterface', 'CustomerInterface' ],' works.

 133     # get all follow up processes
 134     my $FollowupProcessList = $ProcessObject->ProcessList(
 135         ProcessState => \@ProcessStates,

Did you mean the agent interface, or really even if it is only the customer interface?

...after reading it again, you are missing the process activity, and it is not the button which shouldn't appear, am I right?
