inversify-express-middleware throws when returning this.statusCode(401)

[rudfoss]

Expected Behavior

Returning this.statusCode(401) from controller extending BaseHttpController should return 401 status to client.

Current Behavior

Throws:

TypeError: Cannot read property 'headers' of undefined

Possible Solution

Not entirely sure. The code seems to check whether message.content is defined in server.ts, but the compiled code just calls it directly.

// Raw copy from node_modules/inversify-express-utils/lib/server.js
    InversifyExpressServer.prototype.handleHttpResponseMessage = function (message, res) {
        return __awaiter(this, void 0, void 0, function () {
            var _a, _b;
            return __generator(this, function (_c) {
                switch (_c.label) {
                    case 0:
                        this.copyHeadersTo(message.headers, res);
                        this.copyHeadersTo(message.content.headers, res); // Here is the problem
                        if (!(message.content !== undefined)) return [3 /*break*/, 2];
                        _b = (_a = res.status(message.statusCode)).send;
                        return [4 /*yield*/, message.content.readAsStringAsync()];
                    case 1:
                        _b.apply(_a, [_c.sent()]);
                        return [3 /*break*/, 3];
                    case 2:
                        res.sendStatus(message.statusCode);
                        _c.label = 3;
                    case 3: return [2 /*return*/];
                }
            });
        });
    };

Steps to Reproduce (for bugs)

1. Set up a basic project and create a controller
2. Create async handler for an httpGet path
3. return this.statusCode(401)

Context

I'm trying to return 401 errors when users are not authenticated. Preferably I'd like to also return a message, but just the error code is sufficient for now.

Can you show original ts code?
