Review Comment:
The difference are one use alias to struct elements, another one don't use
alias. The one use alias will get rigt answer before this PR, another will not.
I get it from jira ticket.
> I think it would be easier to compare to a DataFrame with the expected
result.
Just check expected result is good for me. I will change it
