Something I’ve noticed with the latest GA version of pulumi. With azure network resources, sometimes (very rarely but common enough to raise an eyebrow) asynchronous tasks like build a Vnet and subnets will sometimes fail at building the subnets because it doesn’t wait for the Vnet resource to complete building. On 📱please excuse typos.

I wonder if for some reason pulumi isn't aware one depends on the other? You could put the Vnet resource in the

dependsOn

property of the subnets to force them to be aware. If that resolves it I'd start looking at whatever outputs are coming out of the Vnet and into the subnets to figure out why the dependency isn't being passed along

good idea. Ill dig a little deeper
