Updates to MySQL tables are not reflecting in PostgeSQL tables with pg_chameleon

Question

I have successfully set up my replication from my MySQL database to my PostgreSQL database using pg_chameleon. However, whenever I insert or update one of my tables on the MySQL database, I get the following error:

replay_replica ERROR: There was an error during the replay of data. ergoscales.kalibrasie_kaarte 
SQLSTATE: 42703 - ERROR MESSAGE: column "null" of relation "kalibrasie_kaarte" does not exist. The affected tables are no longer replicated.

I don't understand the error because there is no null column, and I have ensure the table structures are the same in both databases. I've been using a smaller table as my main tester, and you can see from the create statements, that the table structures are correct:

MySQL:

CREATE TABLE `kalibrasie_kaarte` (
  `id` int NOT NULL AUTO_INCREMENT,
  `Card_Number` int DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=17 DEFAULT CHARSET=utf8mb3;

PostgreSQL:

CREATE TABLE IF NOT EXISTS ergoscales.kalibrasie_kaarte
(
    id bigint NOT NULL DEFAULT 'nextval('ergoscales.kalibrasie_kaarte_id_seq'::regclass)',
    "Card_Number" integer,
    CONSTRAINT kalibrasie_kaarte_pkey PRIMARY KEY (id)
)

This is my pg_chameleon config file, I am unsure if the issue is lying in here somewhere. Is it perhaps the type_override?

I also tried re-enabling the replication for the specific table manually. Works once, but back to square 1 after updating MySQL table again.
