So, of the tmeplates that have script errors, there are two common parts of script that I have confirmed clears the errors when removed from those template page

The first one is "{{Documentation}}" . Yes that is the way that Mediawiki knows to insert documentation . If removing that from the affected templates is what woks, than it works. However, I imagine that {{Documentation}} is the way that templates can transclude the /doc page). Using 2 sets of brackets with the word "Documentation" inside it is the most basic way to bring in a Documentation page.

Interestingly enough, the OTHER code causing these errors is something like this:
{{#invoke:documentation|main|_content={{ {{#invoke:documentation|contentTitle}}}}}}

Seeing "main" in that code would definitely make sense on why Im getting the Script error: "The function "main" does not exist. ". Unlike the {{Documentation}} reference, I am not sure how to remove this without causing issue.
