error in process sentinel: Api 2 unsupported

[joeforan76]

I am trying to connect to a juypter lab instance running on a remote server.

The version of jupyter lab is 4.0.2 and my version of ein is 20230622.1757

I use a ssh-tunnel and connect to the server via ein:login to http://localhost:xxxx (xxxx being the port used for the ssh tunnel). So far so good, I can connect and navigate folders on the server. However when I try to create a new notebook or open an existing one I get the following error

error in process sentinel: ein:kernel-retrieve-session: Api 2 unsupported
error in process sentinel: Api 2 unsupported

It seems that there is a version incompatibility issue, but is there any workaround for this?
