Unexpected error null

[l0rd]

Describe the bug

A few minutes after the first login of a fresh install of Che I see multiple lines with Unexpected error null in Che dashboard container log. Note that errors are logged although the dashboard is not used.

$ kubectl logs -f che-dashboard-85c6f56596-zhlnd 
Starting Dashboard backend server...
Static server's serving "/public" on 0.0.0.0:8080/
