Making an auth provider which can be used on GH Codespaces

[estruyf]

The problem

I'm currently creating an authentication provider and found the following documentation: https://code.visualstudio.com/api/advanced-topics/remote-extensions#callbacks-and-uri-handlers

It states that you need to use vscode.env.asExternalUri as it will correct the GitHub Codespace URL. I have tested this with the provided code sample, but I do not get the URI Handler to work. Locally, it works fine, the message is shown, but online, it does nothing.

Steps

• Open GH Codespace
• Install the VSIX with the code sample provided in the documentation
• Run the sign-in command

The URL it returns: https://estruyf-opulent-capybara-4grqx5g7953754v.github.dev/extension-auth-callback?state%3Dc1511f70c694492e8913f85f97c42b18

• Using the URL from the clipboard, gives the following result

• There is no message in the codespace

Info: removed the auth-complete path check, to be sure, but still nothing.

vscode.window.registerUriHandler({
	handleUri(uri: vscode.Uri): vscode.ProviderResult<void> {
        // Never called
		vscode.window.showInformationMessage(`URI handler called: ${uri.toString()}`);
	}
});```

Anyone an idea how to fix it, or what could be wrong?

It seems it was an encoding issue. vscode.env.clipboard.writeText(callbackUri.toString()); should be vscode.env.clipboard.writeText(callbackUri.toString(true)); to skip the encoding in the URL.
