AS a user, the bot should error out if I supply an invalid sortBy value
SO THAT I know if I'm using an incorrect value

Acceptance Criteria

GIVEN I supply a value to sortBy which isn't valid

THEN an error should be returned

Subtasks

• Add error check
• Add typescript string types
• Update tests

We should also update the typescript to only allow the values in it for further validation
