Still investigating but in the log it shows the secret and the configmap was not found.

Retest failed on 2.5.0-RC3. Referenced configmap still does not have the label added.

Hi Brian @smithbw88 ,
Could you please check if the fix is included in RC3? 
I checked the code in the release 2.5 branch:
https://github.com/stolostron/multicloud-operators-channel/blob/release-2.5/pkg/controller/channel/channel_controller.go#L274
and it shouldn't be possible to show this error message 
```
... channel_controller.go:274","msg":"failed to update referred ...
```
Thanks!
@thuyn-581 FYI.
