The psycopg2.errors.UniqueViolation is an error thrown by the when a user attempts to insert a duplicate key value. In an SQL or SQL-like database a key value is defined when a table is created. This key value is then used to reference specific rows of the table. In order to make calls to these rows unambiguous, this key value must be unique for every row. Any attempt to insert a new row which has a value in the key field that already exists in the table cannot be completed.

The Javascript ReferenceError occurs when referencing a variable that does not exist or has not yet been initialized in the current scope. The ReferenceError: event is not defined usually occurs while using an event handler if the event parameter is either not declared or declared incorrectly. For example, if on an onclick event, the handler does not declare the event parameter, this error is thrown.
