Building a flow using an expression for date and getting this error

(1) ShareShare
ReportReport
Posted on by PowerWork13 2

Unable to process template language expressions for action 'Condition' at line '0' and column '0': 'The template function 'lengthbody' is not defined or not valid.'.

The flow saves without errors and Flow checker has no errors, but when I run the test I get the error as pasted above. The expression I'm using is lengthbody('Select_-_7_Days_Collect_Values')

Relatively new to Power Automate so bear with me 🙂 any pointers greatly appreciated.

    Hi @PowerWork13 ,

     

    This is from a different example I was using but through a conditional action in here to show you the expression for length()

    So here, I am entering an expression length() and then selecting my dynamic content inside the brackets and it looks like this:

    Then saving.  Please try. Save. Resubmit your last test run and let me know.

    Also note:  I am not typing in anything other than length() -- the format including body is included with the dynamic content.
