I upgrade MongoDB Ops Manager from 4.2.4 to 4.4.6. Then it told me that MongoDB Agent, MongoDB Tools are out of date. After I press the upgrade button, the upgrade process is stucked.

The Agent log has the following error:<br>

Interface conversion: interface {} is nil, not float64

Now the Ops Manager is stuck at the "deploying" stage. How to revert to the previous state or fix the problem?

$ kubectl exec -it pod - is useless as the pod are running under a security context which uses user "2000"<br> https://docs.mongodb.com/kubernetes-operator/master/reference/troubleshooting/ is almost useless as we don't have permission to change the pod state. So what's the right way to fix deployment issues when using Ops Manager?
