"error getting cached app state: cache: key is missing" when running `app diff` via CLI

[DerekTBrown]

Describe the bug

I am unable to run the app diff command from the CLI successfully, although the UI correctly returns app diff results.

To Reproduce

argocd app diff my-application --server my-argo-server.local --auth-token ${ARGO_TOKEN} --grpc-web
ERRO[0009] finished unary call with code Unknown         error="error getting cached app state: cache: key is missing" grpc.code=Unknown grpc.method=ManagedResources grpc.service=application.ApplicationService grpc.start_time="2022-09-08T10:19:23-07:00" grpc.time_ms=1258.695 span.kind=server system=grpc
FATA[0009] rpc error: code = Unknown desc = error getting cached app state: cache: key is missing

I was able to resolve this error by performing an argocd login as admin, and then omitting the api-key parameter from the argocd diff command.

It seems like the api-key/server flags are being ignored?

I experience the same using argocd core
