Hi Junrui, Thanks for your answer! Since this exception is not very meaningful, is there a solution or a flink config to filter out or silent such exception in batch mode? When I run some large scale batch jobs in a session cluster, it turns out that the JM log will be fulfilled with this exception which makes it difficult to find detailed execution information about the job.

Hi, This exception is common in batch jobs and is caused by the collect sink attempting to fetch data from the corresponding operator coordinator on the JM based on the operator ID. However, due to the sequential scheduling of batch jobs, if a job vertex has not been initialized yet, the corresponding operator coordinator cannot be found, leading to the printing of this message. This log does not impact the normal execution of the job because the collect sink will keep retrying to send the request.

What is the cause of this exception?
