UNSOLVED martinkooij/MMM-MyWeather: error message about appid

[dankerthrone]

Hi all,
I installed and configured @martinkooij 's module correctly (I think):

{
			module: "MMM-MyWeather",
			position: "bottom_left",
			config: {
				apiKey: "xxxxxxxxxxxxxxxxxxxxxxx",
				lat: "xx.03586",
				lon: "x.06379",
				coloricon: true,
				hourly: '1',
				fctext: '0',
				fcdaycount: "5",
				fcdaystart: "0",
				hourlyinterval: "3",
				hourlycount: "3",
				alerttime: 10000,
				alerttruncatestring: "english:",
				roundTmpDecs: 1,
				UseCardinals: 0,
				layout: "vertical",
				fadePoint: 0.8,
				windunits: "kph"
				
			}

All I’m seeing, though, is this weird error message from a previous fork, I think:

Please set the correct openweather *appid* in the config for
module: MMM-MyWeather. 

The module’s config, however, refers to weatherbit.io as its apibase. My apiKey seems to work there: I manually tested it and it does record “calls made” under my apikey, so that should check out. What am I missing?
