1 month ago Hi,
Apologies for the delay in responding.
Based on the below statement, the error has occurred as the bean name can not be found in the MBeanServer.
Caused by: javax.management.InstanceNotFoundException: debezium.mysql:type=connector-metrics,context=streaming,server=mysql
Bean name is of the form debezium.mysql:type=connector-metrics,context=streaming,server=
Please share your connector configuration if you still face the issue.
Hi,
I run this connector via MSK Connect, but receiving the error at this line in the code. Can help to check why it failed?
