Server error when change to other python kernel

[fecet]

I use conda to manage my environments and I setup this plugin with jupyter on the base environment while set others as different kernels in the jupyer.

However, this plugin works fine in the origin kernel but cant work at all in other kernel. I receive

{"jsonrpc": "2.0", "error": {"code": -32000, "message": "Server error"}, "id": 1}
