Approval workflow - apply to each

[Tricky778]

I'm looking to build a flow using the approval workflow, sequentially moving from 1st approver, 2nd, 3rd up to 5th. 

I only have one approver at each step, the approval flow waits for the approver to respond, it then sends an email to the requestor with the approvers comments, and updates the sharepoint item with both the approver outcome and comments. 

However, because the approval workflow has 'responses comments' and not ' response comments' it treats this as an array and gives me the 'apply to each' grouping. This causes my flow to break once it gets further down the chain, as there is a limit to how many 'apply to each' options you can have. 

Has anyone come up with a way to just capture the individuals response comment so that it doesn't apply the 'apply to each' array grouping? 

Thanks

Hi,

You can use the following expression:

body('Start_and_wait_for_an_approval')?['responses'][0]?['comments']

You can use first() to get the first record in the responses collection and then get the comments or whatever field you need from the collection.  Type the following into the Expression bar.

first(body('Start_and_wait_for_an_approval')?['responses'])?['comments']

Thank you @Pstork1 , your solution worked perfectly

Hello! @Pstork1 This is really close to what I need, but I have five instances where I start and wait for an approval. Using your expression, I get the first one (as the expressions dictates). How would I write it to get comments submitted by all 5 approvers (sending all 5 comments in an email in #6)? Also, how would I write it for each branch? Meaning the approval request for #3 could see #1 and #2 comments and the approval request for #5 could see #1 and # 4 comments.

I actually figured it out! I learned to code HTML in the 90s, LOL, so sometimes my reading of the code is rusty, but I got what I needed by updating the expression portion; ('Start_and_wait_for_an_approval') to the custom name of each of my approvals. So; ('Start_and_wait_for_Inst2') gets me the comments from Intsructor 2! I was able to do that for each of the 5 people who approve and comment in this flow. Woot!
