> when the table type is datagen, Flink will thrown exception ,but the
> exception message is null ;
> My DDL is :
> {code:sql}
> CREATE TABLE datagen_dijie2 (
> f_sequence INT,
> f_random INT,
> f_random_str STRING,
> ts AS localtimestamp,
> WATERMARK FOR ts AS ts
> ) WITH (
> 'connector' = 'datagen',
> 'rows-per-second'='5',
> 'fields.f_sequence.kind'='sequence',
> 'fields.f_sequence.start'='1',
