null response when using _Any scalar type

[newerbie]

Hi, dear team. I defined a custom scalar type _Any and used it as follows: `scalar _Any

type query { configs: _Any }`

But it returns a null response without error when querying the operation configs. What I expect is the response with specific content to be returned. Could you please give me some instructions? Thank you.

Hi,

Could you try naming it without a leading underscore?
