@moorevineyard

yes, thanks.

We had similar errors with older electron versions running with node v18, but you are using the newest mm release.

@moorevineyard

please provide information about your mm-version and node/electron versions.

You find them in the logs, example:

@sdetweil

I submitted a PR

@BKeyport

this is a “feature” of nodebb since release v3.9.1, nothing we can do.

https://github.com/MagicMirrorOrg/MagicMirror/releases/tag/v2.29.0

[2.29.0] - 2024-10-01

Thanks to: @bugsounet, @dkallen78, @jargordon, @khassel, @KristjanESPERANTO, @MarcLandis, @rejas, @ryan-d-williams, @sdetweil, @skpanagiotis.

⚠️ This release needs nodejs version v20 or v22, minimum version is v20.9.0

Added

• [compliments] Added support for cron type date/time format entries mm hh DD MM dow (minutes/hours/days/months and day of week) see https://crontab.cronhub.io for construction (#3481)
• [core] Check config at every start of MagicMirror² (#3450)
• [core] Add spelling check (cspell): npm run test:spelling and handle spelling issues (#3544)
• [core] removed config.paths.vendor (could not work because vendor is hardcoded in index.html), renamed config.paths.modules to config.foreignModulesDir, added variable MM_CUSTOMCSS_FILE which - if set - overrides config.customCss, added variable MM_MODULES_DIR which - if set - overrides config.foreignModulesDir, added test for MM_MODULES_DIR (#3530)
• [core] elements are now removed from index.html when loading script or stylesheet files fails
• [core] Added MODULE_DOM_UPDATED notification each time the DOM is re-rendered via updateDom (#3534)
• [tests] added minimal needed node version to tests (currently v20.9.0) to avoid releases with wrong node version info
• [tests] Added node-libgpiod library to electron-rebuild tests (#3563)

Removed

• [core] removed installer only files (#3492)
• [core] removed raspberry object from systeminformation (#3505)
• [linter] removed eslint-plugin-import, because it doesn’t support ESLint v9. We will reenter it later when it does.

Updated

• [weather] Updated apiVersion default from 2.5 to 3.0 (#3424)
• [core] Updated dependencies including stylistic-eslint

• [core] Updated SocketIO catch all to new API
• [core] Allow custom modules positions by scanning index.html for the defined regions, instead of hard coded (PR #3518 fixes issue #3504)
• [core] Detail optimizations in config_check.js
• [core] Updated minimal needed node version in package.json (currently v20.9.0) (#3559) and except for v21 (no security updates) (#3561)
• [linter] Switch to ESLint v9 and flat config and replace eslint-plugin-unicorn by @eslint/js
• [core] fix discovering module positions twice after #3450

Fixed

• Fixed checks badge in README.md
• [weather] Fixed issue with the UK Met Office provider following a change in their API paths and header info.

• [weather] Fixed issue for respecting unit config on broadcasted notifications
• [tests] Fixes calendar test by moving it from e2e to electron with fixed date (#3532)
• [calendar] fixed sliceMultiDayEvents getting wrong count and displaying incorrect entries, Europe/Berlin (#3542)
• [tests] ignore js/positions.js when linting (this file is created at runtime)
• [calendar] fixed sliceMultiDayEvents showing previous day without config enabled

the package.json contains "webuntis": "latest" so it will always install the latest version of this dependency.

I suspect that there were breaking changes within some versions, you could try an older version (see https://github.com/SchoolUtils/WebUntis/tags).

You have to update package.json with e.g. "webuntis": "2.2.1" and execute npm install in the module folder.

can you provide the logs of system information?

Something like this:

@sdetweil

I won’t stop you from opening an issue …

@sdetweil said in iFrame blank when displaing http://<ipaddress LMS server>:9000/material:

@stephanvdplas i understand, looks like something changed in 31, which can be a bug as well.

you’ve got a workaround in the near term.

id open an issue on the MagicMirror github page with the error and a link to this topic so we don’t lose it.
finding a test environment will be the tough thing

no, we don’t need another issue we cannot solve.

The problem is chromium which is becoming stricter with every release and with every new electron version you get a new chromium version:

electron	Chromium
31.4.0		126.0.6478.23
31.3.1		126.0.6478.185
31.3.0		126.0.6478.183
31.2.0		126.0.6478.127
31.1.0		126.0.6478.114
31.0.2		126.0.6478.61
31.0.0		126.0.6445.0
30.1.0		124.0.6367.243
30.0.9		124.0.6367.233
30.0.8		124.0.6367.230
30.0.7		124.0.6367.221
30.0.5		124.0.6367.207
30.0.4		124.0.6367.201
30.0.3		124.0.6367.119
30.0.2		124.0.6367.91
30.0.1		124.0.6367.60
30.0.0		124.0.6323.0

Maybe related to this changed in Chromium 125.

We have to deal with this and downgrading chromium (indirect by downgrading electron) is no real solution.

I am quite sure about having the config right

sorry, my point is you have to google the error with the keyword “electron” and check if you find something which you can test
