I am not able to run the collection for the POST request while values are fetched from the selected JSON file. Here
TagTypes_CreateOrEdit_name's value is getting generated into the Request Body but for
TagTypes_CreateOrEdit_id's value for null is being replaced by TagTypes_CreateOrEdit_id.
It does work when values are entered into the BODY section, I’m also able to run GET, PUT, DELETE methods using file select.
