When gmaps api returns this error, the client IRoutesMatrixApi doesn't throw any exception and simply returns an empty RoutesMatrixResponse instance.
Is there a way to instrument the client to fail when the response is not 200?
How do I retrieve the list of errors?

As far as I can see in the code, it does throw exception on Status PERMISSION_DENIED. I tested it and for me it throws.
Can you send post the code you are using?

[marco-merola-ef]

I confirm. It doesn't throw any exception in this specific case.
I am using v5.4.9
