Hi @PravK ,
I have made a test on my side, the flow can be triggered by Patch function in PowerApps. I can success to receive the test email.
Can you share more details with your SP list, Flow and Patch formulas in PowerApps?
I guess the error is because there are too many of lookup columns in your SP list , can you delete some and try again? Also can you take a try in new SP list and check if the issue still remain?
Best regards,
Sik
