Azure function activity in ADF V2 timeouts after 4min 7sec, even though in code i have mentioned "functionTimeout": "00:10:00" which is 10mins?

I have created an azure function and its timeout is set to 10mins in hosts.json but when I am triggering it through ADF V2 azure function activity then activity is getting terminated after 4mins 7sec, Can any one guide me what is happening at the backend and why I am getting this behavior? Thanks.

Update: If i run my azure function through ADF or from postman it gives me this error after 4min 7sec:

And if I go to App insights of function App it shows me timeout of 10mins which I think is correct because I am using consumption plan so I know that. But at 4min and 7sec the 502 response which is sent to the client i am not familier with issue. Please guide.

Solution

  • As your function can continue to run as expected even though the 502 error shows, so I think it has nothing to do with your azure function.

    As far as I know, azure function activity just allows 230 seconds for the request in data factory. You can refer to this document. enter image description here

    If you want to request it by postman, you can set the "request time out" in the "settings" of your postman. Please refer to this document.
