I want to update my SharePoint list when the Author does not enter a email in my PeerReviewer Column.

 that is a multiple select (Person/Group) column. When I put in the Condition PeerReviewer is equal to 

empty(triggerOutputs()?['body/PeerReviewers/Email']). it does nor update the List.

Hi @Anonymous 

Please see below. Here 'TestPerson' is 'Person or Group' column type. I have used a compose to map the output. Then in next step I have added an IF condition to check using the below expression

length(outputs('Compose'))

[Anonymous]

I added 

length(outputs( 'Compose' ))

But still get greyed output

Hi @Anonymous 

That means you having no records returning from your step "Get File Properties - For Peer Reviewers". Check the run history and see the data.

Thanks

When I check my history I can see the Data and my PeerReviewers results has [ ] as the value

Hi @Anonymous 

Check your apply to each mapping value?

Is that correct?

Thanks

[Anonymous]

Yes i have I have the Value correct. If I add a email in the PeerReviwers column the condition runs.

Hi @Anonymous 

You mentioned earlier results has [] as the value. This means there is no data under PeerReviewers column.

[Anonymous]

Yes That's correct I want to update my item if their is no data in the column, but when know data is in the column the condition is greyed out.

I got it to work using the length(outputs( 'Compose' )) equal to 0
