All,

 

In creating a blank template to create a file from an email attachment (as well as other situations) I get this message. I have looked online other places, including the Flow Blog but do not have an answer. Anyone help me out?

 

Unable to process template language expressions in action 'Create_file' inputs at line '1' and column '11': 'The template language function 'base64ToBinary' expects its parameter to be a string. The provided value is of type 'Null'. Please see https://aka.ms/logicexpressions#base64ToBinary for usage details.'.
