Error calling ExecuteAsTemplate: type <nil>

Please do not post long console error messages in a topic’s title.

This pollutes the forum and I always aim to keep it clean.
Also long titles will not get more attention.
This topic belongs in the Support category.

I have amended the topic title and re-categorized it, so please do not undo my changes.

Thank you.

P.S. Also please read the Requesting Help guidelines and share the source code of your project.
