It seems that the protocol needs to be configured in the sink-url. Because there is no default value.

I have always been unable to use the canal-json protocol, but switching to the open-protocol protocol works. Both the cluster and CDC versions are v6.1.1, and the reason has not yet been identified.

Could you please share your sink-uri configuration with protocol = canal-json after desensitization?
