Error While Producing Message : Broker: Message size too large

[ysnyldrm]

Hi, we deployed 3 replicas kafka cluster with Strimzi Operator to our kubernetes cluster, so far everything was fine. We configured our broker to fetch big messages, but unfortunately we faced with the Error at tittle "Error While Producing Message : Broker: Message size too large".
This is our kafka object config, also I recreated topics after enable this conf.
kafka:
config:
default.replication.factor: 3
fetch.max.bytes: "15728641"
inter.broker.protocol.version: "3.3"
max.message.bytes: "15728640"
max.partition.fetch.bytes: "15728640"
max.request.size: "15728640"
message.max.bytes: "15728640"
min.insync.replicas: 2
offsets.topic.replication.factor: 3
replica.fetch.max.bytes: "15728640"
socket.request.max.bytes: "15728640"
transaction.state.log.min.isr: 2
transaction.state.log.replication.factor: 3
what am I missing here ?
Thanks for your help.
