Sorry, the errors actually generated by https://github.com/nolimits4web/Swiper/issues/2237 I have this imported for vendor extraction purpose.

I am having the same issue though I have no the nolimits4web/swiper package. Seems like the vendor.js and manifest.js doesn’t get transpiled to es5. EDIT: I found that https://github.com/sindresorhus/query-string is causing this issue.

I am having the exact issue. Do you find any solution to this? I found that downgrading query-string to version 5 seems to solve this issue for now.

I used the query-string-es5 package instead https://www.npmjs.com/package/query-string-es5
