​Executing this query is psql does not give the error​: ​Invalid input
syntax for UUID: uuid_generate_v4(),

This query is almost correct except you have a trailing comma in your
VALUES statement that is going to provoke: syntax error near "," (i.e., you
haven't provided a value for cashier_phone_number)

The query, which you have not yet shown, that provoked the "Invalid input
syntax for UUID: uuid_generate_v4()" must have had the function call
specified within single quotes in order for the server to think it was a
literal value instead of an expression to be evaluated.
