Unsupported activation events: onNotebook:jupyter-notebook

[ariana02880]

Hi Theia,
When I run my theia today, I got this error, could you please help me debug this? Should i use a different version of vscode plugins:
root ERROR [hosted-plugin: 4030] Unsupported activation events: onNotebook:jupyter-notebook, please open an issue: https://github.com/eclipse-theia/theia/issues/new

Here is the python version and theia version i am using:

"@theia/core": "1.19.0",
...
 "vscode-python-features": "https://open-vsx.org/api/ms-python/python/2020.10.332292344/file/ms-python.python-2020.10.332292344.vsix",

@ariana02880 I believe you already opened a similar issue in the past (#11157 (comment)), please see #9867. The activation event and notebook APIs are not yet supported, you'll need to use an older version of the extension which is supported for the given version of theia you have (1.19.0 is quite old).
