Looks like support has been added in version 1.6 on the API. dSYMUrl is now a field on the BuildBundle Attributes https://developer.apple.com/documentation/appstoreconnectapi/buildbundle/attributes

I can confirm we had this issue in our App and the only fix is to erase items from tmp and Caches directories. It took about 3 years for us to get here and only after a DTS ticket did we understand this to be the source of the problem. I am not sure if it is specifically due to storing items in those directories with UUID's in the filename as has been suggested before. Regardless, cleaning up will fix the issue. I would love to see Apple improve how these directories are pruned since the OS should be helping here.
