Simplest of actions.... Had a string type variable Initialized then Set to a string with a bunch of html tags and with dynamic list column value inserted in between.

Flow gives the error upon save "The input parameter(s) of operation 'Set_Email_Body_variable' contains invalid expression(s). Fix invalid expression(s) for the input parameter(s) of operation 'Set_Email_Body_variable'."

Tried with

string(outputs('Get_item')?['body/ReferenceNo'])

doesn't budge. will appreciate some quick pointers! Thanks!

I would try using a compose action rather than a variable based on what you are trying to set the variable to. You can then use the output of the compose action wherever you were using the variable.
