Hello,
I was hoping that I might be able to get some help with an error I am getting with an HTTP action in my Flow. Currently I have what was at one time a very simple and reliable flow to get the staff members from a location in Microsoft Bookings. I am using the HTTP action to do a GET call out to Graph Explorer to retrieve all staff members for the location that was selected previously in the flow trigger.

In the HTTP action I pass the ID for the Bookings location as the output of a compose action and then I pass my Access Token as a string variable. To get the Access Token for my own account, I just grab it from the Graph Explorer site on the "Access Token" tab. It expires pretty frequently, but this flow is only for testing and this always worked in the past.

I was able to pass the access token through to Graph using "RAW" authentication method and putting the access token variable in the "Value" field OR the "None" authentication method and passing the token in the header (Authorization / Bearer {Token}).

However, for the last week or so I now run into the following error in any workflow that uses this HTTP action with these settings.

I have tried to check through the conditional access logs, but I don't see any corresponding failures. The "Request ID" listed in the error also does not correspond with anything in the logs. I checked with our Team that runs the conditional access policies and per them nothing has changed related to continuous access evaluation?
Anyone have any ideas what may be occurring OR if I can structure my flow differently to work around this error? I can use the Graph Explorer directly with no issues. It is just trying to use graph explorer via an HTTP action that runs into the issues.
Thanks,
Chris
