Query with "WITH" clause is failing after calcite upgrade

[Rishabh Kedia]

Hello,

I have a simple query using "WITH" clause:
"WITH tempTable AS (SELECT * FROM PCOLLECTION WHERE
PCOLLECTION.`user_info`.`name` = 'User1') SELECT * FROM tempTable"

and schema such as:
{
"doc":"More information on the user",
"name":"user_info",
"type":["null", "user_info"],
"default":null
}


This query was running properly with Calcite 1.20. But after upgrade to
Calcite 1.31, the above query is failing with the error:
"java.lang.AssertionError: fieldList must not be null, type = VARCHAR"

I looked through the code but couldnt find a reasonable explanation. Any
idea what could be wrong?

Thanks,
