Sometimes I get issue: ‘SyntaxError: Unexpected token I in JSON at position 4’ in Ray Dashboard. it shows this issue for some time and later it automatically vanishes. At the time of error we cannot see anything in Dashboard. All view show same error.
We have Ray cluster with 5 VMs. What is the reason for this issue in dashboard? Is this some dashboard issue or we have to reboot the cluster every week?
What’s the version of Ray are you using?
I had the same error for 1.1.0. The errors occurred when worker connected to the head. If dashboard worked only for head (no connected workers) it was ok.
Can you guys create a Github issue and tag here?
