Anyone seen this error:

gcp:compute:Subnetwork (subnetwork):
    error: 1 error occurred:
        * Cannot determine region: set in this resource, or set provider-level 'region' or 'zone'.

When trying to create a subnetwork? I’ve tried every which way to define the region or zone… Code is currently as follows:

subnetwork, err := compute.NewSubnetwork(ctx, "subnetwork", &compute.SubnetworkArgs{
			IpCidrRange: pulumi.String("10.0.1.0/24"),
			Network:     network.Name,
			Region:        pulumi.String("us-central1"),
		}, pulumi.DependsOn([]pulumi.Resource{network}))

Googled for hours, tried with Pulumi AI, chatgpt, but still no go.
