Hello, have you ever had error
Cannot read properties of undefined (reading ‘branch’)
on launch.js (system file)
i looked into that file and saw error happens on config.self.branch
i have this error when trying to switch scenes dynamically, also after saving changes in scene scripts
thx
Hi @Dima_Romanchuk and welcome,
You mean in editor, in the console your are getting this error?
@yaustar any idea?
Can you post a link to the project. It’s possible you are trying access a scene that doesn’t exist or from another project that you don’t have access to
it’s a private project, i only have properties of writing and reading
project has 1 branch (master)
Can you give me temp access to the project (read is fine) as ‘yaustar’ and also the repro steps on creating the error. I can take a quick look
You have access
project name is “ShowRoom” https://playcanvas.com/project/867478/overview/showroom
to reproduce error you should:
scene switching manages in ChangingScenes.js
thank you
Which scene do I load first?
WalletDev
error happens when switching from this scene
it has to switch to Character scene
vice versa error not happens
I don’t see a X in the WalletDev scene
it’s keyboard button, sorry
It’s very possible the issue is due to the usage of the wallet and the error here:
That might have stopped the scenes from properly being registered on startup. I’ve seen a similar error on Discord with someone else using a wallet
oh, thank you 
we will work in that way
Hmm, that doesn’t seem to be it. Still investigating
i see, i turned off wallet script
ethereum error gone, but not topic one
I think I see the problem.
There’s a global variable normally in the launch tab of a project. (window.config) that is used by launch.js
I think there might be a library or code in your project that is overriding that global and therefore some parts don’t work like scene loading
Edit: in game.js line 406, there is a bit where the global config variable is set to a different object.
To fix this, you will need to use a differently named variable as a global, adding it into a namespace or have it scoped to the Game.js script object
oh, that was really mad error
and now it is solved
thank you, you saved our day
