Hi Team,
 
Could you please kindly check why my power automation workflow can't get response from AI Model (created same account) any more? The same test which worked 2 weeks ago. 
 
many thanks in advance!
BR,
Jin

    Hi Jin,
     
    A 403 Forbidden error usually indicates a permissions or connection issue between your flow and the AI Builder model. Even if it worked two weeks ago, the connection token or underlying permissions may have expired or changed.
     
    A few things you can try:
     
    1. Delete the existing AI Builder connection in your flow.  
    2. Remove the AI Builder action from the flow.  
    3. Make sure your account still has the required AI Builder / environment permissions.  
    4. Recreate the connection and add the action again so it refreshes the authentication.
     
    This typically resolves the 403 issue when the model and flow are in the same environment but the token has become invalid.
     
    Let us know if this helps or if the error persists.
     
    Best regards,  
    Nico
