I have a projected field query which is giving the below error.
Invalid Field Type of Showfield in projected field definition for 'Field_Name'. Unable to add join related fields to the Query.[Error 0x80070057] Unable to execute query: Error 0x80070057 Unknown SPRequest error occurred. More information: 0x80070057
I have checked the ALIAS too. It's the same one which I have used earlier which happens to be a lookup column from the same list. What could be the root cause for this problem?
