[VSCode "OSS"] Extension activation fails: "Can't access Proposed APIs"

[avanderhoorn]

ArchLinux/Manjaro Users: Use https://aur.archlinux.org/packages/visual-studio-code-bin to avoid this problem.

Non-offical distributions of Visual Studio Code can be missing a critical value in product.json file that prevents Visual Studio Live Share from activating. In this case, if you go to Help > "Toggle Developer Tools", you will see stack traces indicating the Live Share extension did not activate due to it using a "proposed API."

To verify this is your issue, check the contents of product.json. The file can be located as follows:

• Windows - C:\Program Files\Microsoft VS Code\resources\app\product.json
• Linux - /usr/share/code/resources/app/product.json
  • Depending on your distribution, exact location may vary.
• Mac - /Applications/Visual\ Studio\ Code.app/Contents/Resources/app/product.json

If the extensionAllowedProposedApi property is missing or you do not see "ms-vsliveshare.vsliveshare" referenced, you are using an unofficial version with this problem. Contact the VS Code distribution owner to get the issue patched.

As a workaround, you can add the following into the product.json:

    "extensionAllowedProposedApi": [         
      "ms-vsliveshare.vsliveshare",         
      "ms-vscode.node-debug",         
      "ms-vscode.node-debug2"    
 ]

For Solus Linux, this was located at /usr/share/vscode/resources/app/product.json

See #215 for this and other issues related to Solus.

EDIT: This particular issue is resolved for Solus with the latest vscode package. libcurl should also be resolved soon.

Same issue here, But I would like to say, My Visual Studio Code is offical distributions.Namely, The Visual Studio Code above can not be missing a critical value in product.json file.

Are you running the latest insiders build, just released?

@grork It worked for me yesterday on Windows 10 with

Version 1.24.0-insider
Commit d29620f2ba89327f51bb6fb2f05dfdd65e2fcafe

Stopped to work after update today:

Version 1.24.0-insider
Commit 8a07c8d935998d1b1153dde0c5b337189d35cea0

I can see that this problem is reproducible on 2 PCs. Both have correct values in product.json

"extensionAllowedProposedApi": [
    "ms-vsliveshare.vsliveshare",
    "ms-vscode.node-debug",
    "ms-vscode.node-debug2"
]

Update, there has been a regression in the latest version of VS Code Insiders which has caused a regression in how they manage proposed APIs. Unfrotunately this has caused issues for us and resulted in the errors you mentioned above. Fortunately, the VS Code team is rolling out a fix to insiders which rectifies this regression and it should be generally available tomorrow.

@avanderhoorn I'm on the latest official insiders build for Windows x64, but the "Proposed API" issue still exists.

I know that this is a closed issue. but here is a Python Script for the lazy to fix that:

#!/usr/bin/env python

import os
import json

VSCodeProductPath = "/usr/lib/code/product.json"

if not os.path.exists(VSCodeProductPath) or not os.access(VSCodeProductPath, os.W_OK):
    print("ERROR: Insuficient permissions or did not find VSCode Product file:", VSCodeProductPath)
    exit(1)

VSCodeProduct = open(VSCodeProductPath, "r")
data = json.load(VSCodeProduct)

# We need to ensure the extensionAllowedProposedApi has the following array:
extensionsToAdd = [
        "ms-vsliveshare.vsliveshare",
        "ms-vscode.node-debug",
        "ms-vscode.node-debug2"
]
print("Before:", data["extensionAllowedProposedApi"])

for extension in extensionsToAdd:
    if extension not in data["extensionAllowedProposedApi"]:
        data["extensionAllowedProposedApi"].append(extension)

print("After:", data["extensionAllowedProposedApi"])
print("Rewriting to file:", VSCodeProductPath)

VSCodeProduct = open(VSCodeProductPath, "w")
json.dump(data, VSCodeProduct,  indent=4)

You file location might changes, this works on Arch Linux, since everytime the package is updated you need to re-fix the product.json file.
