[experiments.baseUrl] External URL -> Duplicate folder structure

[biller-aivy]

Summary

The new metro web bundler has a bug:

When basePath is specified as an external URL, the assets are created in a subFolders.
As a result, when the script is executed on an external website, the external page searches for https://content.app/assets/... but the content is actually at https://content.app/contentapp/assets.... hosted.

What platform(s) does this occur on?

Web

SDK Version

50

 }

It seems like you're attempting to use baseUrl as an asset prefix for hosting on a CDN, this is not how it's intended to be used. We'll need to introduce a second option for configuring external asset prefixes.

Yes, we offer our partner to add our app on their own pages. As example, https://webapp.aivy.app so there you can see the current webpack build but with the links as src in the scripts to our s3 hosted script.

Really need that functionality

[biller-aivy]

@EvanBacon maybe you can give me some advice, than I could try to develop it my myself.

[kouloughli-hemza]

@biller-aivy do you have any success with that so far?
