Square V1 api request not working as per API docs - square-connect

Question

We are experiencing errors with few of Square APIs, it was working a week back, now which is not working as per the documentation, anything changed recently related to square, not able to find out in news : https://docs.connect.squareup.com/api/connect/v1/?q=employee#navsection-roles & https://docs.connect.squareup.com/api/connect/v1/?q=employee#navsection-employees.
Request/Response in question.
Ex 1: With Valid role_ids too it's failing, which used to work 3-4 days back.
