Append error config in VSCode setting.json make VSCode not working. Message: (this.configurationService.getValue(...) || []).filter is not a function

Environment data

• VS Code version: 1.56.2
• Jupyter Extension version (available under the Extensions sidebar): v2021.6.832593372
• Python Extension version (available under the Extensions sidebar): v2021.5.842923320
• OS (Windows | Mac | Linux distro) and version: macOS Bug surr 11.3.1
• Jupyter server running: Local

Expected behaviour

Vscode working normally

Actual behaviour

When ever you click to a file/an extension or what ever you wanna open in VSCode it will show an error

(this.configurationService.getValue(...) || []).filter is not a function

And you cannot open them. As I check the extension add to setting.json and make the file error with message Incorrect type. Expect "array" The setting:

"workbench.editorAssociations": {
    "*.ipynb": "jupyter-notebook"
  },

Remove this config will make VSCode working normal again.

Steps to reproduce:

Install Python extension package

1. Screenshoot

Logs

I’m not able to reproduce this if I enable settings sync, uninstall VS Code and delete settings locally, then reinstall VS Code and resync settings. The only way I see this possibly happening is if you enabled the built-in settings sync across VS Code Stable and Insiders, which is not recommended due to issues like this (setting formats changing between stable releases).

@andy3520 if you can reliably reproduce this problem or if you recall the specific sequence of actions you took to induce this bug, please share them so we can determine if this is a bug or a simple misconfiguration.

Did you have Insiders before? I’m wondering if the built-in settings sync is synchronizing settings between Insiders and Stable.
