grr apply crash with a PrometheusRuleGroup

[MrFreezeex]

If there is a PrometheusRuleGroup and you try to grr apply you got the following crash:

A possible workaround is to use -t Dashboard*.

Are you still having this issue? If so, I'll need more info, e.g. the version of Grizzly you're using and an example of a resource that triggers this outcome.

I'm going to assume this is stale and close this issue. If still relevant, please feel free to re-open.
