Could not start metadata in time

hi everyone!

I am trying to use the server-proxy to start a graphql server to be used by jupyterlab extension.

but it is raising a error. maybe something related to timeout … I checked the issue #81 … but I not sure yet how to fix this problem. any idea? thanks

@saulshanabrook yeah, there’s a ‘timeout’ parameter you can pass - https://jupyter-server-proxy.readthedocs.io/en/latest/server-process.html#server-process-options. You can increase it.
