Module could not be loaded - Hello World

[Dietrich1337]

Hey guys,

I started the Hello World Practice and I am facing an issue now.
I am currently using Znuny 7.0.4 on RHEL9.

Worked everything fine for me and the Menu Button with Hello World is shown in my menu bar. But there is a 500 Internal Server Error, when I click the button. The log gives me this error message:

Code: Select all

Kernel::System::HelloWorld could not be loaded: Kernel/System/HelloWorld.pm did not return a true value at /opt/znuny/Kernel/System/ObjectManager.pm line 255.

I have no idea, what the problem is. I checked ObjectManager.pm at line 255 and there is a requirement for the correct file Ending ( .pm ).
But the file has the correct ending.

If someone can give me an advice, I would be very grateful

Best regards

Hi,

How does Kernel/System/HelloWorld.pm looks like?
