This fixes #1451
and is essentially the same fix done for SPARK-32822
I manually tested this by running the query in the PR apache/spark#29681
We don't support code gen so it was showing up all the time for us.
If someone really wants an automated test I can add it in, but it is totally different from all of the other tests that we have run.
