MMM-Calendar not seem to load .ics

Dennis-010

This is the url of my Kerio mailserver. It is my own dedicated server running in NL.
You asked to xxx out the url right?

If the connection is terminated before completion of the transmission, why is it that if I just paste the url in the default browser on raspberry, I just get to download the .ics file? What am I missing here?

sdetweil

@Dennis-010 the browser has error recovery code that we don’t, probably. they’ve had fetch for a long time. years…

this is one of the.problens w trying to keep up with changes and general supportability .

@sdetweil
Point is, it has worked before… like a charm for over 2 years.
Recently we moved to another house and we have not been using the mirror for 8-9 months, now I reinstalled the OS and modules and now the calendar stopped working.

Is there any way I can try and sort out what the source of this issue could be?

sdetweil

@Dennis-010 I hear you.

none of the code that needs to be debugged is ours(mm) it’s all lower layers.

let me see if there is a hacky way to help you out.

@sdetweil

I’'l be happy to test and try out things or methods to fix this issue.
Thanks in advance

ok, lets try this

cd ~/MagicMirror/modules/default/calendar
cp calendarfetcher.js  savefetcher.js
nano calendarfetcher.js

then insert this line

const Log = require("logger");
const fetchit = require('node-fetch');   //<----- add this line
const NodeHelper = require("node_helper");

then add this line

		const nodeVersion = Number(process.version.match(/^v(\d+\.\d+)/)[1]);
		let fetcher = null //<------ add this line
		let httpsAgent = null;

then later change this

		fetch(url, { headers: headers, agent: httpsAgent })

to this

		if (fetcher === null) {
			fetcher = fetchit(url, { headers: headers, agent: httpsAgent });
		}
		fetcher

then save, (ctrl-o)
and exit nano (ctrl-x)

then

cd ~/MagicMirror
npm install node-fetch@2

then npm start
calendar should come up
mine works…

@sdetweil
This seem to work like a charm, thank you for fixing this.

Now…when I want to add 2 more url’s I get a new error:
For each of the new url. Both from the same domain.
is it possible to have a hacky line for that as well?

@Dennis-010 this sounds like an ics data format problem

change this line in config.js

logLevel: ["INFO", "LOG", "WARN", "ERROR"],

to

logLevel: ["INFO", "LOG", "WARN", "ERROR","DEBUG"],

then start MM like this

pm2 stop all
cd ~/MagicMirror
npm start > somefile.txt 2>&1

wait 15 seconds
then in the same window as where you did npm start do
ctrl-c
and then examine the somefile.txt to see where that error is…

i’d like to see the ics file entry for that event
npm start
