I have in my Azure IoT architecture a Stream Analytics (SA) connect to an Azure Function.

Sometimes I have this error of my SA:

"Send Events: Azure Function Output Adapter failed to write events"

and in the JSON message of the error I find this description:

"Message": "Failed to write events. Error encountered after writing [0] batches [...]
"Type": "AzureFunctionOutputAdapterFailure"

I don't have error on the Azure Function but it stopped work. Has anyone ever had the same problem?

  • I set the correct version of the TLS of the Azure Suite, but it doesn't work yet. It seems related only to the Stream Analytics – davide.ferrari Apr 03 '19 at 12:43
  • @davide - does the Azure Functions code compile with no errors? and have you unit tested the function independently? You shouldn't have to change the TLS version any longer. – Sid Ramadoss Apr 11 '19 at 18:00
  • @SidRamadoss It happened sometimes so it's very strange. I think the Azure Function it's too complex. I'm following this tutorial: https://learn.microsoft.com/en-us/azure/azure-functions/functions-best-practices to re-write the structure of the function to an Azure Logic App. – davide.ferrari Apr 12 '19 at 07:13
