Review Comment:
We can use a minimal case to reproduce the error, e.g.,
```scala
@Test
def testCalcMergeWithCorrelate(): Unit = {
util.addTemporarySystemFunction("str_split", new StringSplit())
val sqlQuery =
"""
|
|SELECT a, r FROM (
| SELECT a, random_udf(b) r FROM (
| select a, b, c1 FROM MyTable, LATERAL TABLE(str_split(c)) AS T(c1)
| ) t
|)
|WHERE r > 10
|""".stripMargin
util.verifyRelPlan(sqlQuery)
