Hi,
I am using google ads api for creating billing setup, then got this error message:
"errors {\n error_code {\n request_error: UNKNOWN\n }\n message: \"The error code is not in this version.\"\n location {\n field_path_elements {\n field_name: \"operation\"\n }\n field_path_elements {\n field_name: \"create\"\n }\n field_path_elements {\n field_name: \"payments_account_info\"\n }\n field_path_elements {\n field_name: \"payments_profile_id\"\n }\n }\n}\n".
why it return this "message: The error code is not in this version" while I am using API v3?
