Rest API xml not working for Get Datasource User and Get Group Users

[2operate]

Hey

We're having an issue with the following list of API calls:

• https://docs.microsoft.com/en-us/rest/api/power-bi/gateways/get-datasource-users
• https://docs.microsoft.com/en-us/rest/api/power-bi/groups/get-group-users

When requsting the response in JSON (default), it works fine, but switching the accepted response type to XML, we're getting a HTTP 500 - An error has occurred

Hi,

As far as I’m concerned, the response type of the Power BI rest API is in the format of JSON instead of XML

Thank you very much!
