Hi,

I am running Kong version 1.3.0rc1 databaseless with the kubernetes ingress controller 0.5.0. I ran into an issue where Kong appears to be unable to register plugins on routes. When looking in the Kong pods’ error logs I see this message repeated:

```
2019/08/06 17:43:54 [error] 35#0: *19056 lua entry thread aborted: runtime error: /usr/local/share/lua/5.1/kong/runloop/balancer.lua:249: attempt to index local 'healthchecker' (a nil value)
stack traceback:

```

In the Kubernetes logs I see this in the Ingress Controller:

```
E0806 17:44:16.035853 1 controller.go:125] unexpected failure updating Kong configuration:

```

Any help with understanding these errors, would be much appreciated.

Thanks,
