I have defined a https://www.pulumi.com/registry/packages/gcp/api-docs/compute/packetmirroring/ in a Pulumi project, but whenever I now run

pulumi up

for a stack with that resource, it always produces an update preview like this:

Type                            Name                          Plan       
     pulumi:pulumi:Stack             example                                
 ~   └─ gcp:compute:PacketMirroring  ids-packet-mirroring  update

and when the

details

option is selected, there is no diff. What might be going on here and how could I debug this? I tried looking at more verbose logs but didn't see anything that looked explanatory.
