HTTP with Microsoft Entra ID (pre-authorized) - 401 Error

(2) ShareShare

Posted on by 4
Hi everyone,
 
I use "HTTP with Microsoft Entra ID (pre-authorized)" connector to retrieve metadata from power bi dataflows using for exemple the endpoint :
"/metadata/v201606/cdsa/dataflows/[dataflowID]/contentandcache".
 
The connection is using those parameters :
Authetication type : Connect with Microsoft Entra ID
 
Since the past 3 days, all my flows using this connection are failing, after working for several years :/
Despite my attemps to recreate the connection (even with another user account), I could not find a way to repare this.
NB  : we do have access to the workspaces that contain the dataflow within power bi service.
 
I have requested my internal IT admin to track any changes on pbi admin portal parameters, also waiting for them to confirm if DLP have changed in a way that could affect that.
In the meantime if someone has an idea on what is happening, I am all hears. It looks to me that Microsoft recently changed something related to that connector, but not sure what...
Thanks
