hswlxc opened a new issue, #7219: URL: https://github.com/apache/seatunnel/issues/7219
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened   When tableSchema is obtained from tablemap through tableId, a null pointer exception occurs, but tablemap has values, so there should be a problem when comparing Tableids ### SeaTunnel Version 2.3.5 ### SeaTunnel Config ```conf env { execution.parallelism = 1 job.mode = "STREAMING" checkpoint.interval = 5000 read_limit.bytes_per_second=7000000 read_limit.rows_per_second=400 } source { Postgres-CDC {
