Make a web frame with Raspberry Pi in 30 minutes

Please use the thread below to discuss the related blog post:

Good morning
I just tried to recreate this project. The Device is registered in the Dashboard and the Raspberry with the display shows the Balena logo.
I also entered a url at the LAUNCH_URL variable, but the display still shows the Balena logo.
When I look at the log file, there are many errors here.
Can someone help here?
