Qr code from zeus preview does not work

[vvidov]

I created simple zeus Todo app v1. Nothing is changed I would like it to test on my device GTR 3 Pro.
I can test it on simulator.
I can load other mini app from that page https://bigdigital.home.blog/2022/12/21/zepp-os-devices-support/
but if i run zeus preview, I get an qr code
zeus preview
info building...

success The QR code will expire on 2025-02-13 11:11:17.
and zepp app got
'Download failed, error code : null'

What is wrong in my case? What is missing?

Usually similar errors occur when you try to install an application not for your model. Make sure that the deviceSource in the app.json file is specified correctly.
It's also rare, but there are just failures at the provider and the file is not loaded. But in this case it helps to just try again in a few minutes.
