JSON Schema Compliance URL

Hi - using ReadyAPI 3.55.0 I'm setting up JSON Schema Compliance assertions for REST services. I can enter the url for the rest service openapi.json and it's fine, like this:

https://genericwebsite.com/openapi.json

Then, when I add the reference in the schema assertion url to the specific method, anything I put after the .json seems to change nothing, even when incomplete:

https://genericwebsite.com/openapi.json#/components/schemas/GetServiceFooResponse
Works the same as:
https://genericwebsite.com/openapi.json#/components/schem

So, is anything after the .json in the schema assertion url recognized?

Thanks.
