Multiple web sources for multiple extensions overwrites s3 folder #868
Description
Describe the bug
We don't support multiple UIs as part of the same project.
Creating a project with multiple extensions and UIs will overwrite the s3 folder instead of returning an error.
Workaround
Quoting @shazron
The tooling doesn't have the concept of partitioning the S3 bucket for different web extensions because of the above rule. When uploading to S3, it will empty out the namespace's partition every time thus this is what you are seeing.
One possible workaround is to use aio app use and create/use a different secondary workspace to deploy your other web extension (skip deploying actions), and use the primary workspace for your main web extension and actions. There might be CORS issues with the secondary workspace web assets with the primary workspace actions however, but you can get around this by setting the appropriate headers: https://developer.adobe.com/app-builder/docs/guides/deployment/setting-response-headers/
