What happened?
Using a collection as a query param results in "Collections as query parameters are deprecated and will be removed in a future release", and using a collection in a path is forbidden: "Path parameters must be primitives or aliases"
What did you want to happen?
The generally accepted way to retrieve multiple resources in a single HTTP request seems to be including it in the URL, either as a way query param or part of the path (1, 2, 3 ). Forcing queries retrieving multiple resources to be in POST would deviate a bit from the general "GET for retrieving resources, POST for creating/retrieving resources"
