Rejected rename promise results in empty message box

[dbaeumer]

Extension code:

'use strict';
// The module 'vscode' contains the VS Code extensibility API
// Import the module and reference it with the alias vscode in your code below
import * as vscode from 'vscode';

// this method is called when your extension is activated
// your extension is activated the very first time the command is executed
export function activate(context: vscode.ExtensionContext) {
	vscode.languages.registerRenameProvider('plaintext', {
		provideRenameEdits: () => {
			return Promise.reject(new Error('Only locals can be renamed'));
		}
	});
}

// this method is called when your extension is deactivated
export function deactivate() {
}

• open plain text file
• execute rename
• you get an empty message box.

I would expect the message that I pass in the Error of the rejected promise.

That only works when rejecting the promise with a string not with an Error or other types...

I tested the string case as well and it produced the same result.

Sure about that? TypeScript is implemented and shipping like that and works well with insiders

[dbaeumer]

I tested it and it didn't work. I was using the latest insider on latest Electron. This crashed on my so I went back and now the strings case is working.

@Tyriar @bpasero FYI. There seems to be more broken with the new Electron build.
