This reminds me of #37925 which was fixed by removing the reference to sourceMappingURL in 11add87

Maybe we should tackle all incorrect references to .map files for javascript files at once and not one by one?

[simonmaass]

Yeah we got quite a few .map errors also from other files in sentry... there are quite a few in Magento_PageBuilder

There's 184 references for sourceMappingUrl showing in pagebuilder alone lol.. I was trying to tackle some of this for work and now I am not so sure LOL

I fixed it by downgrading file "lib/web/underscore.js" to 1.13.2v, and writing: bin/magento s:up, bin/magento s:s:d -f, bin/magento c:f
