While trying to update to new release via dashboard Even though the previous version was updated successfully Dashboard shows error and stalls subsequent update. When tried to stop and start app `replicatedctl` throws **array index out of bounds** error.

Error Trace:

```

Can you try running `kubectl get pods`

Yeah everything seems to be working fine.

Mani, there should a a label on the replicated pod `tier: master`. You can see the failing command that looks for it in the `/usr/local/bin/replicatedctl` scrip. Can you check what labels the pod has:

```bash
kubectl get pod replicated-<generated stuff> -o yaml | grep -w -5 labels

```

Can you also run the following command?

```bash
kubectl get pods -l tier=master

```

I think I found the reason for this issue.  
This arises when I change my default namespace in context. This eventually means `/usr/local/bin/replicatedctl` should use `-n default` in the `kubectl` commands. Screenshot attached.  
Should I raise an issue in any GitHub repo?

Works fine after updating namespace in `/usr/local/bin/replicatedctl` as follows

```auto
 sh -c "kubectl -n default exec -c replicated $flags \
          $(kubectl get pods -n default -o=jsonpath="{.items[0].metadata.name}" -l tier=master) -- \
          replicatedctl$push $(printf "%s" "$opts")"

```
