Hallo zusammen,

ich habe ein Script, das im Visual Studio Code funktioniert.

const mqtt = require('mqtt');

Ich habe versucht das Script mit dem JS Adpater von Iobroker zu starten.

Leider funktioniert es nicht.

Das Problem ist folgendes: in der Zeile 31

bekomme ich folgende Meldung:
Property 'connect' does not exist on type 'typeof import("mqtt")'

Kann mir jemand bitte weiter helfen?

[karloslb]

@cinimod sorry, bin neu im Forum. Es hat ein wenig gedauert.

@karloslb

Alles gut, war nicht bös gemeint. Es war nur nichts zum auswerten da

Ich bin da leider raus.

Ignorieren! Der Javascript-Editor meckert bei Attributen, die er nicht kennt.

Nein, leider nicht. Ich bin nicht so fortgeschritten.
