I'm testing out creating my first Azure Function in ADF and stuck on the body JSON format.
I'm using the output from a filter:
{"name":"@{activity('FilterFilesXML').output}"}
My filter output is:

and the input for function is showing this:

I'm getting an Error code: 3608
Cause: The Azure function details in the activity definition may be incorrect.
Recommendation: Fix the Azure function details and try again.
So must be my format but can't see were it is wrong, ideas?
Thanks
