Hi team, When serviceAccountName Pointing to a non-existent SA, Stuck and unable to create pod

serviceAccountName: fake-must-gather-operator

operator pod no err log; mustgather no err log

Misspelled words will increase the difficulty of troubleshooting.

I hope print the err message in status (SA ******* not found in namespace ***)

Create MustGather with fake SA
serviceAccountName: fake-must-gather-operator

    1.Create a MG CR with   serviceAccountName: fake 

jitli@jitlideMacBook-Pro:~/work/src/test/must-gather$ cat supportloggather-negative.yaml 
apiVersion: operator.openshift.io/v1alpha1
kind: MustGather
metadata:
  name: support-log-gather-jitli 
  namespace: must-gather-operator 
spec:
  serviceAccountName: fake
  uploadTarget:
    type: SFTP
   ........

    2. no pod be created 
jitli@jitlideMacBook-Pro:~/work/src/test/must-gather$ oc get pods -n must-gather-operator
NAME                                    READY   STATUS    RESTARTS   AGE
must-gather-operator-6b9b84dfb4-rpmtd   1/1     Running   0          11m

Although the operator pod's warnings are close to suggesting a SA issue, they are not direct.
