S3 Sink Connector Fails when use schema registry

We’re using Amazon S3 Sink Connector Connector and we were able to use it with AWS MSK to stream messages to S3 without any problems.

However, when we enable the configuration to use a schema registry (hosted on another server) to deserialize the message and convert it to json, the plugin shows the error below:

We have already verified that the MSK environment communicates with the environment where the schema registry is hosted.

We’re able to consume the message and deserialize it programmatically but not using S3 Sink
