Overview

In the following PR, rule GetCollectionResponseSchema raised an error that appears to be a false positive, caused by two paths that share the same "/providers..." suffix.

Azure/azure-rest-api-specs#30656 (comment)

My first question is whether this scenario, where two paths in a spec only vary by a /subscriptions/{subscriptionId} prefix, but return different data types, should even be allowed?

@bdefoy, @rkmanda: What do you think?

If not, then the rule is technically correct to raise an error here, but the error message is misleading.

If so, then the rule will need to be updated to allow it. Inspecting the code, I believe the root cause is around here, since it only considers the path after the last index of "/providers". This code would need to be updated, to consider the prefix before this as well.
