e: Use of uninitialized value $DataValue in pattern match (m//) at /opt/otrs/Kernel/Output/HTML/TicketOverview/Small.pm

[GLM]

Hello,

OTRS 6.0.23 on Debian 10

/var/log/apache2/error.log is registering this error (several at same second) each time a certain agent (unknow) action is done. I can't trace to the agent action that triggers the error.

[Tue Apr 7 11:55:35 2020] -e: Use of uninitialized value $DataValue in pattern match (m//) at /opt/otrs/Kernel/Output/HTML/TicketOverview/Small.pm line 1636.

Any ideas?

Thank you in advance.

Best regards.

Hi,

check the TicketOverview settings in system configuration and reset it if needed.

Hello,

Thank your for your response.

Can you please point me to the TicketOverView settings? Searching Sysconfig for "TicketOverview" returns 20 results and I don't know what must be reset.

Thank you.

Best regards.

After upgrading from 6.0.23 to 6.0.27 the error was gone.
