Calling Azure Function from Azure Data Factory Gives 404 Error

Rob Bowman 221

I have an Azure Function named "SendTemplateEmail" that has an HTTP Trigger.

I'd like to call this from an Azure Data Factory Pipeline.

I've created a new linked service and configured as follows:

I've configured the Azure Function task within the ADF Pipeline as follows:

[![enter image description here ]4]3

When I run the pipeline, I get the following error:

Works if using Web Task

If I make the call from the pipeline using a web task configured as follows then the call to the Azure function is successful:

Is there any way to figure out the URL the pipeline is trying to reach?

Hi @Rob Bowman ,

Thanks for using Microsoft Q&A!!
I have tried with both using Function App activity and web activity and it works fine in both the cases.

I am only getting similar error if I disable my function app or passing an incorrect name to the Function Activity.
In which region your function app is ? Also, what's the plan you are using ?
Can you please try deploying your function app in a different region and validate if this works for you.

Thanks

Hi Saurabh,

The region is UK South. The function app is enabled (the call from the ADF web task wouldn't work otherwise), but the problem could be that I'm giving the incorrect name. That's why I asked if there's any way to know the URL that data factory is requesting?

Thanks,
Rob.

Hi @Rob Bowman ,
ok, get it and like you said the name may not be correct but I don't think of any ways to get URL information. I am checking internally if there is any way to get the information. I will let you know if there is any.

Thanks

Hi @Rob Bowman ,
As per internal discussion it looks like there is no way you can get the exact url which pipeline is trying to reach. You may need to check with the support team as they have access to internal logs from where you can get the required information.
Please let me know if you have any questions.

Thanks
Saurabh
