Kafka Message Size Too Large Error in RHOCP 4

Issue

• The Kafka server accepts messages up 10MB
• Vector collector is reporting an error: MessageSizeTooLarge for the Kafka output
• The error message in the collector states: Message size too large
• The Vector Kafka Sink is affected
• The service call failed with no retries or retries exhausted
• Even if it's set the tuning option maxWrite, it's observed the MessageSizeTooLarge in the collector for the Kafka output
• If it's used Fluentd as collector, it works

• Vector collector shows the error:
