400 error when starting an instance in a custom subnet: URL is malformed

[jppentti]

We are trying to create instances in a custom subnetwork and are getting a 400 error from GCP (Stacktrace below).

According to https://cloud.google.com/compute/docs/reference/rest/v1/instances/updateNetworkInterface the subnetwork value provided should be an URL and from the the stacktrace it looks like the plugin is using the subnetwork name property

@jppentti, @matti-cujo, it should be fixed in the latest bug fix update 0.7.2.

Indeed, thanks! I closed #26 since your fix is better.
