  +=== Invalid column name error
  +
  +This error happens very rarely. If you receive an error with the message `Illegal prefix '@' for column: x, from schema: y, table: z`, and your table doesn't have such a column, it is a Vitess vstream link:https://vitess.slack.com/archives/C0PQY0PTK/p1606817216038500[bug] that caused by column renaming or column type change. It is a trasient error. You can restart the connector after a small backoff and it should resolve automatically.
