Describe the bug
When registering some types, I get the following exception:

To Reproduce

2. Load the assembly at runtime
3. Register the entities and types using my ObjectTypeUtils attached:
   the ObjectTypeUtils use reflection to create ObjectType from given Type t
4. Then when get the error you can see in the stack trace.

Thank you for reporting this issue.

I have fixed the error message now. It basically says that you object has no valid fields.

Since you are on V9 I recommend using the schema builder:

SchemaBuilder.New()
   .AddType(YOURPOCOTYPE)
   .Create()

The bug is fixed with 9.0.0-rc.1 which should be completed in the next 30 min.
