Lane.GetLinks | InvalidOperationException: Sequence contains no elements

[NiklasDanz]

When calling client.Lane.GetLinks(someLaneID), I get the following error:

InvalidOperationException: Sequence contains no elements

Hello @NiklasDanz, sorry for the delayed response.
This line of code causes the exception, I guess: link
The question is what causes the result to be empty. Are you able to debug this?
There is also a related TODO here: link
Would be great if you could do a PR, or alternatively provide a sample scenario where this occurs.
