Property selection is not supported on values of type 'String'

Hi all,
 
I recently created a flow to email anyone who appears in an excel column to tell them they've got an overdue item. But I get this error message in my Filter Array: The execution of template action 'Filter_array' failed: The evaluation of 'query' action 'where' expression '@equals(items('Apply_to_each')?['PSM (HUB)'], items('Apply_to_each'))' failed: 'The template language expression 'equals(items('Apply_to_each')?['PSM (HUB)'], items('Apply_to_each'))' cannot be evaluated because property 'PSM (HUB)' cannot be selected. Property selection is not supported on values of type 'String'.
 
 
I was following this suggestion: Send users single email with multiple Excel rows (Power Automate) . Is there anyway I can change the property type so it isn't a string?
 
Here is my entire flow:
 
 
Many thanks in advance,
 
Freddie

    Thanks for the reply @MS.Ragavendar. Please see screenshots. I believe they're email addresses. They're hyperlinks in the spreadsheet.

    The issue might be the Mail column which you referring in the excel might be having any non valid email format for e.g., Instead of the string it might have number column because of that filter array might not be possible. 
     
    Can you please share the output of the compose table, how the data is available for the property eMail.
