How to reproduce
This is because the table contains fields with the identity attribute, which can be divided into two situations
The fields written in Flinksql contain the identity field
The fields written in the Flinksql task do not contain the identity field
Execution is required when writing the identity field value
If the written field does not contain an identity field, do not execute it. Otherwise, this problem may occur. Therefore, we will first determine whether the written field contains an identity field
