Hey sorry for the long wait hehe.
It is hard to test different settings because as soon as i save settings all cache gets cleared and that also gets rid the error. But it looks like if i disable JS processing on FVM it gets rid of the error, but as soon as i enable it the error comes back.
You can check this site for an example of the error:

removing /js/jquery/jquery-migrate.min.js from the default ignore list works as a workaround but i don’t think that is a smart way to fix the error?
