@Injectable()

    constructor(private agendaService: AgendaService) {
    }
}

const injector = ReflectiveInjector.resolveAndCreate([
    AgendaService
]);

const server: Server = injector.get(Server);

// etc
@Injectable()
export class AgendaService {
constructor(){
        this._agenda = new Agenda();
        // edit: the ausent SOME_VAR causes the error
        this._agenda.database(process.env.SOME_VAR);
}
//etc

[eassymo]

it's caused by an ausent enviroment variable

process.env.SOME_VAR

if it does not exists throws this error:

Cannot read property 'match' of undefined

Adding enviroment var, fixes the problem.

issue updated.
