Yes, you think it's easy, but it will take more time for someone else to prepare the environment.
The best way is that you provide reproducible statement and configuration, which saves time for contributors who investigate problems and resolves issues faster.

it's not about the environment or configuration yet, it's just a case, you
just need to verify sharding table with a group-by operation, when your
terms route to more than one table, then need to merge the result, as the
bugs report described I provide a snapshot.it's clear where the bug
happens. did you try it

I don't know if this exists in 5.3.2, cause 5.3.2 is still not public to
the maven repository, so it's hard for me to try 5.3.2, but this question
is easy, you just need to see when you perform a query with group-by
operation, and your sharding key route to more then one table, and bingo,
NullPointorException invokes. it's quite easy to replay that issue, just
try it.
