@nkc when MagicMirror starts up the console log displays a section with runtime info. Could you post that?

@nkc great, thanks will look into it

@nkc where can I find that module? not on Github, not in our 3rd party list

@sdetweil I found this link. I cannot confirm it is what nkc is using.

@msimon360 thx… looked up by name… weird…

anyhow
sendSocketNotifcation uses json.stringify/parse under the covers… both are sensitive to data structure nesting

i would guess there is a json bug…

the code is in the node helper

                       fetch(getInfoUrl, options).then((res) => {
				if (res.ok) {
					console.log(`\x1b[32m[SEMS-API][${res.status}] - Received Solar Data\x1b[0m`);  <--- this came out in the debug
					return res.json();
				} else {
					console.log(`\x1b[31m[SEMS-API] - Something went wrong\x1b[0m`);
				}
			}).then((data) => {
				// return the data part of the api response
				self.sendSocketNotification("SOLAR_DATA", data["data"]);  <-- looks like the error spot... no data validation was done from receipt to here
			})
