Description
Previously if the dry runner encountered a table with a predicted schema with a column type it did not recognise it would output the standard pydantic error for an Enum saying that the vale is not one of the allowed values. But it didn't tell you what column this was for and what value was supplied so it made it hard to debug. This intercepts the pydantic error and outputs a better error message.
