queryDepthLimit

The maximum depth a query can have in a single request. Depth refers to the amount of nested levels allowed in the body of query. The default value is 0 (or unspecified), which indicates there's no depth limit. If you set a limit, it can be between 1 and 75 nested levels. This field will produce a limit error if the operation falls out of bounds.

Note that fields can still be set to nullable or non-nullable. If a non-nullable field produces an error, the error will be thrown upwards to the first nullable field available.
