> --------------------------------------------------------------
>
> Key: FLINK-28527
> URL: https://issues.apache.org/jira/browse/FLINK-28527
> Project: Flink
> Issue Type: Bug
> Components: API / Python
> Affects Versions: 1.15.1
> Reporter: Xuannan Su
> Priority: Major
>
> The bug can be reproduced with the following test
> {code:python}
> def test_flink(self):
> env = StreamExecutionEnvironment.get_execution_environment()
> t_env = StreamTableEnvironment.create(env)
> table = t_env.from_descriptor(
> TableDescriptor.for_connector("filesystem")
> .schema(
> Schema.new_builder()
> .column("name", DataTypes.STRING())
> .column("cost", DataTypes.INT())
> .column("distance", DataTypes.INT())
> .column("time", DataTypes.TIMESTAMP(3))
> .watermark("time", "`time` - INTERVAL '60' SECOND")
> .build()
> )
> .format("csv")
> .option("path", "./input.csv")
> .build()
> )
> @udtf(result_types=DataTypes.INT())
> def table_func(row: Row):
> return row.cost + row.distance
> table = table.join_lateral(table_func.alias("cost_times_distance"))
> table.execute().print()
> {code}
> It causes the following exception
> {code:none}
