Imported modules in v10 are empty

[gpoitch]

Using prebid through npm, importing the individual modules does not seem to include any of the code since v10. It just imports an empty module. Building it doesn't complain. Just noticed during runtime that there were errors about the modules missing and the output being smaller.

For example:

import prebid from 'prebid.js'
import 'prebid.js/modules/concertBidAdapter'
import 'prebid.js/modules/gumgumBidAdapter'
import 'prebid.js/modules/rubiconBidAdapter'

prebid.processQueue()
export default prebid

Adjusting to the full path is a workaround:

import 'node_modules/prebid.js/dist/src/modules/concertBidAdapter'
// ...

Thank you for the report! I believe this is due to incorrect sideEffects in package.json, to be fixed with #13773; could you confirm that you're using webpack?

Yes, webpack!
