Import Project into ExB DEV Editon : custom widget cause export/download fail. (dev server crashes)

FredericPoliart_EsriAU — Fri, 18 Apr 2025 00:54:12 GMT

I am using ExB DEV edition V1.17 , importing a project from our Enterprise Portal -- which works really well!
In the imported project, we use a custom build widget, hosted on Amazon S3 -- all OK
In Experience Builder developer edition, I use the IMPORT > Import from My Account

It connects correctly to my Portal and I can clone my ExB project into my local Developer Edition - OK
When running the ExB experience App, the custom widget works ! - OK

Now if I try to export the project from Dev Edition into a big distribution .zip file, it causes the server to crash (see screenshot below) It looks like it tries to add the https://{mywidgeturl}/manifst.json as if it was a concatenated file path.

New rule : if the file you want to include in the .zip starts with https:// do not try to prefix the dist-prod path, and do not try to add it inside the .zip file. leave it as-is (skip/ignore)

Thank you for the post! Currently, apps containing custom widgets are not supported for download. We appreciate your feedback and will consider this for a future enhancement.
