ray: [Dashboard] The webui failed to load 0.8.6

What is the problem?

Ray version and other system information (Python version, TensorFlow version, OS):

Ray: 0.8.6 Local webview: Mac OS 10.15.5 + Chrome | 83.0.4103.116 (Official Build) (64-bit) Server: ubuntu 18.04 The port is mapped via ssh -L 8265:localhost:8265 <server node>.

Reproduction (REQUIRED)

I’ve recorded a video. The web dashboard first works normally (loading), but after few seconds, it failed to load.

I have verified my script runs in a clean environment and reproduces the issue.
I have verified the issue also occurs with the latest wheels.

@mfitton I could reproduce with this script.

import ray
from ray.cluster_utils import Cluster

cluster = Cluster()
cluster.add_node()
cluster.add_node()
n = cluster.add_node()
ray.init(address=cluster.address)
cluster.remove_node(n)
import time
time.sleep(30)

@mfitton & @rkooo567 Please let us know if there is anything we can do as users to assist with resolving this issue. Thanks for your continued work.

Hey folks! This should be working on the master branch. The issue, as it turns out, is that when a node was leaving the cluster, there was a missing piece of data that was causing the page not to load. That data has now been marked as optional in the master branch, so this issue should be resolved.

I tried to recreate on the master branch, and I was unable to, and due to the code changes, I believe this to be fixed. That said, I would be very grateful if someone who initially ran into the issue could validate that they don’t encounter the issue on the master branch.

Assuming it is working as I believe, it will be fixed in the next release.
