Postgres trigger function error

I am trying to write a trigger function in postgress 9.5. But i get an error when trying to execute the script.

My trigger:

CREATE TABLE batch (
  id bigserial PRIMARY KEY,
  batch_type varchar(60) NOT NULL,
  external_id varchar(255),
  status varchar(20) NOT NULL,
  CONSTRAINT unique_external_id UNIQUE(batch_type,external_id)
);

      CREATE TABLE batch_wip (
      batch_id BIGINT NOT NULL,
      PRIMARY KEY (batch_id)
    );

    CREATE OR REPLACE FUNCTION insert_records_into_batch_wip()
      RETURNS trigger AS
    $BODY$
    BEGIN
      IF NEW.status = 'STARTED' THEN
        INSERT INTO batch_wip(batch_id) VALUES(NEW.id);
      END IF;
      RETURN NEW;
    END;
    $BODY$
    LANGUAGE plpgsql;

    CREATE TRIGGER new_batch_record_inserts
      AFTER INSERT
      ON batch
      FOR EACH ROW
      EXECUTE PROCEDURE insert_records_into_batch_wip();

Error Iam getting,

Can someone figure out what wrong with my sql script?
