Apply to each no longer working

Good morning,


I did create a workflow with an approval, this was working fine.

Today I try to test it again but I got the following error:


Approval start:







I'm unable to select an output from the previous steps. This was working last week.


Can you help me with this?


Thank you in advance,


Evert Hoegee

Hi @evert,


The error message means that the return value of dynamic content Responses is null. Please add a Compose action to check the return value of Responses.

I have made the following test, apply to each is working properly.


If you are still having the issue, please feel free post back.
