Undefined array key "operation" when creating series

[mic-men]

Describe the bug
When a new series is created, an error is thrown: Undefined array key "operation".
The error is thrown every time the series is selected. Old series are not affected.

To Reproduce
Steps to reproduce the behavior:

1. Create a new series via the ILIAS GUI.
2. Only a title is given, everything else is left with default settings.
3. Save
4. Error message is shown. The series is created at the OC side.
5. The series is shown as ILIAS object. When clicking on it the error pops up again.

Expected behavior
The series should be created without error.

• ILIAS version: v8.13
• PHP version: PHP 8.0.30
• Plugin version: v8.1.1
• Opencast version 14.6

Additional context
Maybe there is a relation to issue #311 ?

[rfcmaXi]

Confirmed with Plugin version: v8.1.1 / PHP version: PHP 8.0.30

[rfcmaXi]

In our test installation, I no longer receive the error after the plugin-update has been executed via CLI Command (without mentioned pr)

[mic-men]

The proposed fix #329 solves the problem in our environment.
