Missing required configuration "taskId" which has no default value

[thijsnissen]

Hi! After updating from version 15.0.0 to version 15.0.1 we encounter the following issue:

ERROR org.apache.kafka.connect.runtime.WorkerTask - WorkerSinkTask{id=foo-bar-0} Task threw an uncaught and unrecoverable exception. Task is being killed and will not recover until manually restarted.

org.apache.kafka.common.config.ConfigException: Missing required configuration "taskId" which has no default value.
