lookAheadHours #36

Open kamcioo opened 2 years ago

kamcioo commented 2 years ago

Hello,

unfortunately I can only one time get information from DWD after I change the content of the “Look Ahead Hours”. I get always this message after I have asked second time for the informations: MOSMIX request failed: TypeError: Cannot read properties of undefined (reading 'lookAheadHours')

Thank You in advance, kamil

It works with this example of the function lookAheadHours (every injection one hour is added)

var hours = flow.get('hoursAhead');
if (  hours === undefined){
    hours = 0;
} else{
    hours += 1;
    }
flow.set('hoursAhead', hours);

msg.payload = {lookAheadHours : hours};
return msg ;
