K8 Installation cannot Spawn server

I am installing JH through FROM jupyterhub/k8s-hub:2.0.0. I have modified the theme for it. The server runs fine and no issues except when i select the environment i want to spin up. In the hub pod I get

Can you start by trying the standard Z2JH Helm chart (version 3.0.0-beta.3) without any customisations- if that doesn’t work please give us us much information as possible to reproduce your error, e.g. how was your k8s cluster setup?
