I use vscode to connect to the jupyter service of my remote server, but the server log reports an error and cannot be used normally.

Problem description: I used docker to install a python environment, and then used jupyter and public IP proxy to come out. It can be used normally through the browser, but when trying to connect to vscode, the code cannot be run. The kernel can be queried on vscode. Then I looked at the startup jupyter service log and found this error. Since this is my first time using vscode to connect to a remote jupyter service, I would like some help. Thanks!
