cannot load Swagger - The reader's MaxDepth of 64 has been exceeded

[marina-p]

When loading the Swagger document at https://github.com/Azure/azure-rest-api-specs/blob/main/specification/network/resource-manager/Microsoft.Network/stable/2022-05-01/networkInterface.json, the new default MaxDepth=64 in NewtonSoft.JSON (as of 13.0.1) is exceeded (call stack below). An earlier version of this document could be loaded without issues by earlier versions of NSwag.

Is there any way currently to set the MaxDepth through the public interface when loading an OpenAPI document? If not, would it be possible for you to expose this, or increase the maximum?

I can work around this by setting JsonConvert.DefaultSettings locally in my project. Closing the issue.
