1- Initialize a 'string' variable to "email@domain.com",
2- Append to variable with dynamic column email
3- Extract substring from created string to eliminate last extra comma ',' e.g.
"email1@xyz.com","email2@xyz.com","email3@xyz.com",
Even though the variable is initialized in first step why then on save it gives error
"Flow save failed with code 'InvalidVariableOperation' and message 'The inputs of workflow run action 'Set_EmailRcptTo_variable' of type 'SetVariable' are not valid. The variable '{EmailRcptTo}' must be initialized before it can be used inside action 'Set_EmailRcptTo_variable'.'."
Please note I am doing following:
1- Initialize string variable
2- Append to string variable
3- Set string variable
Requirement:
1- Create a string initialize it with a sample email all quotes and comma separated "abc@xyz.com",
2- Add to the string dynamic email values from SP column, all enclosed values with quotes "" and a comma e.g. "email1@xyz.com","email2@xyz.com","email3@xyz.com",
3- Remove the last extra comma character
