calendar fetch fails with header size exceeded, breaking node js change

forum topic https://forum.magicmirror.builders/topic/14257/overflow-with-calendar

see https://github.com/nodejs/node/issues/24692

node has made the max header size 8000 down from 80,000. we have some bad servers which are sending the data in the headers too…

the url above is invalidated(by me) so it could be posted here… I can advise someone else the corrected url

the workaround --max-http-header-size=??? some number doesn’t work

 node ./node_modules/.bin/electrons/electron.js --max-http-header-size=10000

I upgraded to latest stable node, 14.15.3

same error

I added the maxHeaderSize value to the request options

		const opts = {
			headers: {
				"User-Agent": "Mozilla/5.0 (Node.js " + nodeVersion + ") MagicMirror/" + global.version + " (https://github.com/MichMich/MagicMirror/)"
			},
			maxHeaderSize: 12000,
			gzip: true
		};

same error…

i don’t know any other approach to resolving this… help

fails on 2-14-develop as well, on node 14.15.3 also

i do not think we need to implement any fixes. I was waiting til the user confirmed it worked for him. but it worked for me.

and the workaround is easy to do

I appreciate your help
