Internal Server Error on Save when HTTP Action has "@..." in the Body.

I'm working on a flow that creates private channels in a Team. This functionality isn't available through the provided Teams connector so I'm using the generic HTTP action for now. Through Graph Explorer and Postman I can create private channels by creating an Azure application and using the example found at When I create the same action in Power Automate and click the Save button I get the following error message, "Encountered internal server error. The tracking Id is '<UNIQUE ID>'.". The issue appear to be with "@..." appearing in the body of the HTTP POST action. If I remove the "@" symbol I can save the flow with no issues. If I change "@odata.type" to something else like "@randomstuff" I still get the save error. Unless someone knows of an alternative, the Graph API for creating private channels or adding members to a channel must include that "@odata.type" property. Performing other GET or POST requests against channels using the HTTP action work without issue.


Here is what my action looks like.

Hi @amorrow ,


I would make a test later and reply here once the issue is confirmed.
