Errors when creating model from sql (redshift)

All sql I've tried to use results in the same error:

VARCHAR[null]ERROR: Error while parsing data type parameter.

This has happened on very simple create table statements as well as more complex versions. 

Example sql 

CREATE TABLE addresses (
address_id bigint NOT NULL ,
address_line_1 varchar(250) NOT NULL
);

Error message:

ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]ERROR: Error while parsing data type parameter: VARCHAR[null]
