How to fix 'collection' invalid section type error in custom code liquid?

[Khaal]

I have created a private collection using custom code liquid however there is an error.

The error as follows:

Liquid error: Error in tag 'section' - 'collection' is not a valid section type

I understand that there are several users facing the same issues. Can I check if anyone has actually have any solutions for this case?

Thank you

It sounds like the issue may be with the collection template.
