BehaviorSubject requires a default value to be passed:

messageSource: BehaviorSubject<[string,boolean]> =
       new BehaviorSubject<[string,boolean]>(['', false]);
                                             ^^^^^^^^^^^

when you want to update value you should also pass array:

this.messageSource.next(['foo', true])

Also, you can use object as a value instead.
