Completely black in iframe on Dakboard Raspberry Pi 4 #301

Closed webash closed 2 months ago

webash commented 3 months ago

Describe the bug An iframe of the London Tube board has been embedded in a Dakboard dashboard which is then being displayed on a Raspberry Pi 4 running DakOS 4. When showing the Dakboard page, the iframe stays black except for the cookie prompt (or shows nothing at all if cookies are accepted with ?acceptCookies=true.

In previews on my local browser, the iframe displays as expected. On the Raspberry Pi's browser, the full webpage (https://www.leddepartureboard.com/london-tube/HUBWSM) displays as expected

To Reproduce Steps to reproduce the behavior:

  1. Go to https://www.leddepartureboard.com/london-tube/HUBWSM
  2. Grab the URL and embed in an iframe in Dakboard
  3. View the Dakboard on DakOS on Raspberry Pi 4
  4. See black box only

Expected behavior The typical departure board should display, like it does on other browsers.

Screenshots Here it is working fine in the preview on my own machine image Here it is only being black on the Dakboard / DakOS Raspberry Pi 4 PXL_20240626_133947615_resize

Additional context Add any other context about the problem here.

@benfl3713 is there a way that I can force the iframe to load without the custom font?

Hi @webash Sorry in the delay in getting back to you on this, I've been rather busy with other things so haven't had much time to focus on this project.

I took a look at this iframe issue and found it was throwing errors relating to how websites within iframes have different permissions to normal websites.

I've made some code changes to address these issues and have just deployed the changes now. You should be able to try it again now and see some results hopefully!

I thought I was going crazy. I hadn't looked at it since a few days after my post, until yesterday when I setup the Dakboard PC that this is embedded on in our building lobby and saw it was working. Hadn't seen this reply until just now. Yes all working! Thanks for picking this up! Legend!

iframe now works on Dakboard embed as expected. Closing issue.
