Trying to check if a Email column has anything

[jmon]

Hello, 

I am trying to check if a email column has anything in it. I have tried the name of the column and then there are 3 different options and all keep saying null. When I check for null it doesn't work.  I have also tried to check the length of the column. 

The error

Unable to process template language expressions for action 'Check_if_there_is_a_Reviewer' at line '0' and column '0': 'The template language function 'length' expects its parameter to be an array or a string. The provided value is of type 'Null'. Please see https://aka.ms/logicexpressions#length for usage details.'.

Any thoughts?

Hi @jmon ,

You could try:

empty(XXX)  is equal to true

or

XXX is equal to null

I think this link will help  you a lot:

Wow thank you, I was not aware of this. 

All good now.

@v-bofeng-msft Can you look at this code, I must be missing something small because it keeps going as false. 

My condition is this. 

empty(body('Get_file_properties')?['Reviewer#Claims'])
