Azrue Function TIME out issue always timing out at 3.8 min +-

Question

We have created an Azure function in C# to process some .csv files and save each record to a database. The problem is that the DB is a third party and we have no control over the SP's being used and saving a record can take 4-5 seconds each. So if I have a .csv with 100 records the time exceeds the default time out of the Logic app (single tenant nonconsumption) I have modified my host_json to have the following. and did the run-test and it takes about 4-5 min with 100 records.

"functionTimeout": "00:30:00",

but it still times out with an error Http request failed: the server did not respond within the timeout limit. Please see logic app limits at https://aka.ms/logic-apps-limits-and-config#http-limits. It times out at 3.9 min (Logic App time out)

Is there any why to increase the Logic app time out?

Answer 1

For longer running operations, use an asynchronous polling pattern or an "Until" loop.

To work around timeout limits when you call function that has a callable endpoint, you can use the built-in Azure Logic Apps action instead, which you can find in the designer's operation picker under Built-in.
