> Doesn't the query shown in the PR description look the same as
`sql("select employer.company, employer.company.name, employer.company.address
from contacts")` in `SchemaPruningSuite`? It is basically querying a nested
struct (`employer.company`) and a few nested columns inside the struct.

Our prod have a very complex job and spark version is 3.1.2. I have tried to
put it in UT but it run as normal. But this error actually happen in our prod.
With this patch our job can run well.
