[Bug]: resolveDependency() in core/middleware/integrations swallows error message

[grzs]

Describe the Bug

Tried to load a custom integration after a successful yarn build, but failed with dependency error.
I didn't have a clue so I started node with debugger and then I could see the exact error message.
It would be crucial to see what is exactly missing.
Here is the debugger output:
