Json Query

[Odin Guillermo Caudillo Gallegos]

Hi.
I have a schemaless table based on json files.
If i do a query like the following:

select dj."MyField" from jsontable dj;
it gives me the error "ERROR: internal error: Columns projected from
default.jsondigilant is not found."
So i can't use alias if i'm using a schemaless table?
Thanks!
