Some rows in the Postgres table can generate CDC while others cannot

Question

I have a Postgres DB with CDC setup.

I deployed the Kafka Debezium connector 1.8.0.Final for a Postgres DB by

POST http://localhost:8083/connectors

with body:

{
    "name": "postgres-kafkaconnector",
    "config": {
        "connector.class": "io.debezium.connector.postgresql.PostgresConnector",
        "tasks.max": "1",
        "database.hostname": "example.com",
        "database.port": "5432",
        "database.dbname": "my_db",
        "database.user": "xxx",
        "database.password": "xxx",
        "database.server.name": "postgres_server",
        "table.include.list": "public.products",
        "plugin.name": "pgoutput"
    }
}

I noticed some strange things.

In same table, when I update rows, some rows can generate CDC, but other rows cannot generate CDC.

And those rows are very similar except for id and identifier are different.

-- Updating this row can generate CDC
UPDATE public.products
SET identifier = 'GET /api/accounts2'
WHERE id = '90c21719-ce41-4523-8ad1-ed6b21ecfaf1';

-- Updating this row cannot generate CDC
UPDATE public.products
SET identifier = 'GET /api/notworking/accounts2'
WHERE id = '22f5ebf3-9594-493d-8aa6-649d9fbcefd2';

I checked my Kafka Connect container log, there is no error neither.

Any idea?
