Describe the feature or resource

When I called the AlloyDB HTTP client to delete the instance, and then waited for the operation, I always see the following error saying proto: (line 15:3): missing \"value\" field":

{"severity":"error","timestamp":"2024-12-09T09:43:51.458Z","msg":"Reconciler error","controller":"alloydbinstance-controller","controllerGroup":"[alloydb.cnrm.cloud.google.com](http://alloydb.cnrm.cloud.google.com/)","controllerKind":"AlloyDBInstance","AlloyDBInstance":{"name":"alloydbinstance-qh7bag2wlrpcrdy","namespace":"qh7bag2wlrpcrdy"},"namespace":"qh7bag2wlrpcrdy","name":"alloydbinstance-qh7bag2wlrpcrdy","reconcileID":"a63fddd8-13c2-42a8-a710-8737c07d4405","error":"Delete call failed: waiting delete instance projects/[project-id]/locations/europe-central2/clusters/[alloydb-cluster]/instances/[alloydb-instance]: proto: (line 15:3): missing \"value\" field"}

The instance will be deleted successfully though.

We should figure out why this error is returned to avoid the suboptimal UX.

Here is a snapshot about where the error returns:

k8s-config-connector/pkg/controller/direct/alloydb/instance_controller.go

Line 374 in 09d53c4

err = op.Wait(ctx)

The passed-in DeleteInstanceRequest contains the correct AlloyDB instance name.
