Failed with configuration of Replicator

Hi,

I’m working with a POC by using the Confluent Platform.
In our use case, we set up a Confluent Platform for Kubernet on Azure AKS (which simulate the on-Premise Confluent Platform on Kubernet kluster) and a Confluent Cloud Cluster (standard version). On the Confluent Cloud, we need to set up a Replicator. The data in a topic on Confluent Platform for Kubernet will be replicated to the topic on Confluent Cloud. We have created a Custom Connector Plugin for Replicator on the Confluent Cloud Cluster. But the Confluent Replicator Connector is always failed.

We use the default security setting in Confluent Cloud Cluster. And use SASL_PLAIN Authentication for the Kafka on Confluent Platform for Kurbent.

The configurations for the replicator on Confluent and the replicator configuration can be found in my next messages (because of the limitation with maximal one picture in a post)

The replicator connector is failed and below are some part of the logs:

Can someone help me to find out, which configuration may be wrong or is there other configuration missing?
