CORS issue while listing extensions


Maybe I’ve created first topic in wrong category. Decided to create another topic here.

I have a CORS issue, while trying to get extensions from JupyterLab Extensions Manager. JupyterLab was deployed via JupyterHub zero-to-kubernetes v1.1.1 helm chart, which is spinning in VPC.

I found similar question here, but not sure about exact solution.

Could you provide any ideas where to dig or how to fix CORS error?
