Hi, we were using jupyter hub 3.x and recently moved to Hub 4.1.5 with helm chart jupyterhub-3.37, we are using docker images, and our base image is taken from Quay

I use templates for UI customisation,
and I took the templates from jupyterHub git repo, branch 4.x,
when the jub is 3.6 the servers are spawned, with the templates, but when I switch to 4.1.5 the spawning is failed, and I have been digging on this for two days, is any one specify do we need to pass extra filelds in the /hub/spawn POST request when we submit the form.

Are you missing an XSRF parameter? It’s impossible to make any other suggestions without seeing your template changes and your error messages.
