      The UNNEST function will cause the Delayed Retry Strategy For Lookup doesn't work

      When I use the UNNEST funcation in my sql statement to achieve array expansion, the Delayed Retry Strategy For Lookup has no effect. 
      The retry is not performed according to the configuration, and there are no logs or exceptions.

      I tried flink on yarn mode and standalone mode and it doesn't work.
      See the attachment for the error statements、success statments and source dml in case. 
      It is easy to reproduce in sql-client

      Here are some information:

       

      index value
      version flink-1.16.1
      source kafka
      source data canal-binlog data
      source format json
      look up source mysql
      sink kafka
      sink format json

       

       

      Please developers judge whether my case is a bug. 
      Looking forward to your answer!
