Addon causes exception

[jthulhu]

When trying to change the position of a javascript asset to "As External Document", save and click "Write To Templates", Anki shows the following error:

Error
An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.
If the issue only occurs when add-ons are enabled, please use the Tools > Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.

Thanks for the notice,
If you don't need it right away, I'll fix it the next time I update the add-on :)

I don't actually need it, I was just toying around to see what the add-on has to offer but writing directly into templates is exactly what I needed.
Btw, it would be cool if one asset could be used by multiple note types :-) .

one asset [...] by multiple note types

That's a much requested feature. I'll certainly have a look at that next time I'm working on the add-on. Problem is, Asset Manager is already probably my most complex one so-far 😅 , and I'll need some time to implement it cleanly, without making everything entirely unmaintainable.
