Review Comment:
Hi @rubenada , sorry for bothering you, I have found the
[CALCITE-5145](https://issues.apache.org/jira/browse/CALCITE-5145) is an
another scenario for wrong type mis-match, I looked the
[pr-2818](https://github.com/apache/calcite/pull/2818) @yingyuwang submitted
and found a general solution for the two scenarios, please review when you are
available.
