If you see above in apply to each you are adding three things.
Apply to each action in power automate corresponds to a loop in any other language like a for loop in Java language.
In that if you see you just pass 1 array in it. Not 2-3 arrays at the same time. Likewise here also you can only send one array in it. But if you see you have added three things in it.
But I think in your case you apply to each is not actually required.
Do you want to do this:
- A form is filled.
- Then an approval is send to the approver.
- Then you want to send the response details to someone.
If not can you explain your scenario and share your entire flow, I will restructure it.
So, do the following changes in your flow:
Delete the apply to each action, by clicking on three dots.

Just directly add response in the email.

If you want comments from approval part, just select the responses comment. This will not add an apply to each loop. [ Probably in your case you selected comments coming from microsoft forms which created an extra apply to each loop]

I hope this helps 🙂
