Problem importing external module!

When I try to import my external file "brain.js" into the script "main.js", I get the following error:

'import' and 'export' may only appear with 'sourceType: module'

I'm trying to import a neural network file that I've downloaded from a CDN. I fail to understand why I'm getting this error. Why does it throw me this error? Works fine when I use it in my JS/Node projects...

You can't import in scripts in event sheets. (Those are really inside functions, and the JavaScript language disallows import and export inside functions.) The syntax is also wrong for the module specifier (it should be "./brain.js").

This is what the 'Imports for events' script is for - anything you import there will be accessible by scripts in event sheets. However the script you've included does not actually export anything (it uses a different module system), so you'll need to load it differently anyway.
