What happened?

I follow the documentation for create a cluster minecraft.

When I create my proxy, the pod not ready because in the container I have a error:

Could you provide me the Kubernetes LoadBalancer resource Shulker has created? Especially the status part (don't hesitate to mask out the IPs if some are listed, I just need to see the shape, not the values)
