Azure function fails when called via "Azure Function" but succeeds when called via "Web" in ADF

Nem Lasica 0 Reputation points

I have deployed an Azure function that runs successfully when tested from within the Azure Function App portal (Code + Test), Postman as well as the Web activity inside ADF, however, it consistently fails when called via the Azure Function activity with the below error:

Call to provided Azure function 'xxx' failed with status-'Unauthorized' while invoking 'POST' on '' and message - 'Invoking Azure function failed with HttpStatusCode - Unauthorized.'.**

The function authorization level is set to "Function" and when calling the function via the Azure Function activity in ADF I provide the function (tried both, master and default) key via "x-functions-key" in the headers, yet it continues to fail.

Any ideas? Thanks!
