Cannot get MMM-EmbedURL to show any sites

Rapsberry Pi 4, MagicMirror v2.29.0

I have a week-old install working for all modules except MMM-EmbedURL. I am trying to get two, local ip cams to display a feed over http. These feeds work fine in the Chromium desktop browser. Here’s an example of a URL:

http://10.0.0.51:50081/ui3.htm?t=live&cam=Doorbell&maximize=1

I have tried other URLs, including the examples, but nothing shows up, not even an error. This is the last module to load for me, and no errors are present for any module. There are not any other broadcasts or messages related to this module afterwards. The header used does appear, confirming the module is loaded.

[LOG]   Connecting socket for: MMM-EmbedURL
Sockets connected & modules started ...

In case there are any known issues with other modules, here’s a list of what’s installed and working, across 4 different pages with MMM-pages:

WallberryTheme
WB-clock
WB-weather
MMM-CalendarExt3Journal
alert
updatenotification
clock
MMM-homeassistant-sensors
MMM-CalDAV
Pinfo
calendar
MMM-Pir
MMM-MoonPhase
MMM-NHL
MMM-MyStandings
MMM-EasyPix.
MMM-BGSS_1 (copy/tweak of MMM-BackgroundSlideshow)
MMM-GroveGestures
MMM-NotificationTrigger
MMM-EmbedURL

Here’s the top of my config.js, as well as the relevant module configuration:

let config = {
        electronOptions: {
                webPreferences: {
                        webSecurity: false,
                        webviewTag: true,
                        },
                fullscreen: true,
                alwaysOnTop: true,
        },

and

{
                       module: "MMM-EmbedURL",
                       position: "upper_third",
                       header: "Embed-URL",
                       config: {
                               updateInterval: 120,
                               embedElementType: "webview",
                               attributes: [
                                       "frameborder=0",
                               ],
                               embed: [
                                       "http://10.0.0.51:50081/ui3.htm?t=live&cam=Doorbell&maximize=1",
                                       "https://www.youtube.com/embed/dIHr96KqfDI",
                               ]
                       },
               },

I’d appreciate any help on this, and let me know if there’s something else I can add or provide to resolve.

@wishmaster270

Just went back in and realized these were commented out in my config.

ignoreXOriginHeader: true,
ignoreContentSecurityPolicy: true,

I added them back in, and success! Now to find a way to config the page to not need a login, but its huge progress. Thanks!

@unaccomplished can you look at the messages where you start MagicMirror

if you are using pm2, then
pm2 logs --lines=50

may show them

typically I recommend NOT using pm2 when adding and changing modules as it makes access to the logs harder…

I see

@unaccomplished

I put one of my MM web pages in the embed list and it also doesn’t show… altho the embed content is in the MM elements page view
and the page works correctly when viewed in a browser (the page is hosted by MM)

never tried the module before

Hi,

just tried your config in my setup and everything worked as expected.

The question is…where are the differences in your and mine setup.

As a first try you can replace embedElementType: "webview," with embedElementType: "iframe,".

If the embeded pages does not block embedding iframe should work and you do not weaken any security settings of the electron browser.

Additionally you can replace "frameborder=0", with "frameborder=1",. You should see two boxes at least then. Even if the sites could not be embedded.

@sdetweil Are you sure you set the security settings of electron? Without them electron will not support webview and will not display anything.

Are you sure you set the security settings of electron?

no… I viewed that as optional if doing webview…(electron javascript content) but I am viewing an html page. (altho hosted by MM)

If do use the build in electron browser to view the mirror you can use Webview instead

my config

      {
  module: "MMM-EmbedURL",
  position: "top_left",
  header: "Embed-URL",
  config: {
    updateInterval: 120,
    attributes: [
        "frameborder=0",
    ],
    embed: [
        "http://localhost:8090/modules/MMM-Config/review/",
        "https://cnn.com"
    ]
  },
},

It seems this is the most relevant error in the log:

Here are my error logs:

The two wrapper errors and the two Wallberry warnings have been perpetual, but don’t seem to affect anything. If you have any insight on these, I’d appreciate it.

I also noted this from the out-put log:

0|MagicMir | ### OTHER:    timeZone: America/New_York; ELECTRON_ENABLE_GPU: undefined
0|MagicMir | [2024-12-04 17:53:26.965] [LOG]   Electron's cache successfully cleared.

and later in the same log:

0|MagicMir | [2024-12-04 17:53:34.289] [LOG]   resizing done!

I don’t think these are errors, at least not in the context provided.

Hi,

just tried your config in my setup and everything worked as expected.

The question is…where are the differences in your and mine setup.

As a first try you can replace embedElementType: "webview," with embedElementType: "iframe,".

If the embeded pages does not block embedding iframe should work and you do not weaken any security settings of the electron browser.

Additionally you can replace "frameborder=0", with "frameborder=1",. You should see two boxes at least then. Even if the sites could not be embedded.

@sdetweil Are you sure you set the security settings of electron? Without them electron will not support webview and will not display anything.

I updated the config as requested, once without, and then with “iframe”.

{
                       module: "MMM-EmbedURL",
                       position: "upper_third",
                       header: "Embed-URL",
                       config: {
                               updateInterval: 120,
                               embedElementType: "iframe",
                               attributes: [
                                       "frameborder=1",
                               ],
                               embed: [
                                       "http://10.0.0.51:50081/ui3.htm?t=live&cam=Doorbell&maximize=1",
                                       "https://www.youtube.com/embed/dIHr96KqfDI",
                               ]
                       },
               },

Without switching to iframe, the frameborder made no difference. Now with iframe, I have two blank boxes appearing.

so @wishmaster270 will have to help more

Sorry, is it a formatting error in my comments, or in my config file?
