CosmosDB: Guid IDs instead of object IDs of Vertex?

Is there any sample / way we can work with a typed value like Guid instead of object? for the Vertex Id? Object is extremely error-prone…

We have already tried to work with Guid directly or a struct-based abstractions. This works so far on reading, but on vertex writing diff argument exceptions are thrown like

Gremlin.Net.Driver.Exceptions.ResponseException: InvalidRequestArguments: 

ActivityId : a6f0053f-ab75-4b99-92bb-6f0934182c84
ExceptionType : ArgumentException
ExceptionMessage :
	Value of variable _b is not a constant type. Cannot assign complex values to groovy variable. (Parameter 'value')
Source : Microsoft.Azure.Cosmos.Gremlin.Core
	HResult : 0x80070057

We could not find any reference to this in the docs either.

Thanks for your help!

Immutability is king. Everything is immutable. If you call something on e and return e, you’ve done nothing. Return the result of Configure.XYZ.

BTW the IVertex interface does not have to be used. Gremlinq is just fine without. Of course, IVertex defines the object Id in the first place but it’s not necessary.
