Full backtrace

Steps to reproduce it:
1. Go to luna.amazon.com/?isLGTV=true
2. Log in and try to start a game

Upon starting the game, the following assertion is hit in debug, and it crashes in release mode. The code is introduced in 285820@main and no crash happens before that.

ASSERTION FAILED: textureIndex < m_textures.size()

Adding Jani in CC, in case he has any thoughts about this :)

[Jani Hautakangas]

Good that there's this assert in the code. I tried to reproduce but luna amazon service is not available in my country

[Philippe Normand]

When I had to deal with geo-blocked websites in the past I used a VPN (mullvad), maybe you have access to one?

[Jani Hautakangas]

thanks for the hint. I'll check with VPN

[Jani Hautakangas]

I got VPN now and I'm able to access the games.
What parameters are used to start the browser? With WPE MiniBrowser luna service gives me "Unsupported Browser", "It looks like you're trying to play on a browser or browser version that isn't supported."

[Philippe Normand]

You need a couple env vars:

export GST_PLUGIN_FEATURE_RANK=rtpisacpay:0,rtppcmupay:0,rtppcmapay:0,rtpg722pay:0,rtppcmapay2:0,rtppcmupay2:0
export WEBKIT_DISABLE_SANDBOX_THIS_IS_DANGEROUS=1


also enable the webrtc websetting
and this user-agent websetting: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36

[Jani Hautakangas]

Still cannot get game running. Now application requests game controller setup but WPE doesn't detect PS controller even though it's working otherwise. Game controller icons show that keyboard should be ok to use but it still it requests gaming controller.

[Philippe Normand]

I don´t know if MB supports gamepad input. Cog does, if you use the  --gamepad=manette option.

[Jani Hautakangas]

Ok thanks, I'm able to reproduce the issue now
