Hi Team

 

Does anyone can help me with this error;

 

InvalidTemplate. Unable to process template language expressions in action 'Parse_JSON' inputs at line '1' and column '2546': 'Required property 'content' expects a value but got null. Path ''.'.

 

I am trying to convert JSON file from Azure Stream Analytic job to be CSV file using Azure Logic App, how do i troubleshoot this error? Kindly please help, thanks.
