Dealing with empty Person fields in Flow

[Courtney Prothero]

I am trying to build a flow connected to a SharePoint list with a few person fields. However if I try to access any of the person fields and they are blank, it chokes. I even get an error if I try to test the field for null or empty. I'm not sure how to proceed. These are not required fields. 

The error I get is something along the lines of:

The template language expression 'triggerBody()?['PersonField']['DisplayName']' cannot be evaluated because property 'DisplayName' cannot be selected.

Doesn't seem to matter which field I'm trying to get: Claims, DisplayName, Email, etc

Hi @Courtney Prothero,

I would look at setting variables as shown here:

You will need to use conditions to then check the value of the people fields before doing anything with them.

Thanks for the quick answer.This helped me clarify things a little. In case it helps anyone else, here's what I had to do.

Initialize variables for each field (no value). 

Try a condition against each person field, testing the Object field itself (not Claims, DisplayName, etc) for null. 

Then if it wasn't null, I could assign the right value to the variable. 

I think my problem was that I was testing my conditionals against a value in the object, not the object itself.

Thanks again.
