Method may only be called on a Type for which Type.IsGenericParameter is true after upgrading ServiceStack app to NetCore 3

After upgrading a ServiceStack based api app from NetCore 2.x to NetCore 3.0, my Angular app is receiving errors from the api when the server tries to return the response from what I can see.

ServiceStack.Host.Handlers.HttpAsyncTaskHandler: 2019-10-25 21:50:26,248 [22] DEBUG ServiceStack.Host.Handlers.HttpAsyncTaskHandler - CreateRequestAsync/requestParams:
ServiceStack.Host.Handlers.HttpAsyncTaskHandler: 2019-10-25 21:50:26,249 [12] DEBUG ServiceStack.Host.Handlers.HttpAsyncTaskHandler - CreateRequestAsync/requestParams:
ServiceStack.ServiceStackHost: 2019-10-25 21:50:26,276 [4] ERROR ServiceStack.ServiceStackHost - ServiceBase<TRequest>::Service Exception
System.InvalidOperationException: Method may only be called on a Type for which Type.IsGenericParameter is true.
   at System.RuntimeType.get_DeclaringMethod()

Any tips as to what this issue is?

Upgrade to v5.7.1 as per @mythz excellent suggestion.

"In that case can you download the latest v5.7.1 on MyGet as it's sounds like the GetRawBody() issue in .NET Core 3.0 which has since been resolved."
