cors problem with snaps quickstart

[seddik11]

Hi,

I was following this tutorial to start my first snap however I encountered this cors error when i try to connect.

BTW I am using github codespace.

Thank you

Hi @seddik11! There may be multiple issues here, but regarding CORS, snaps have a null origin, so any API that your snap needs to talk to needs to allow null origin.

If you want to share your codespace so I can see the code feel free to do so.

Hi thank you for your reply.

I didn't change anything in the code. I just used this command yarn create @metamask/snap your-snap-name to create the app. Except this line I changed from localhost to the domain where the app is runnning

because of this

I got this error also when i try to connect

There may be an issue in the create-snaps package. What version of node are you running? If you can't get it to work, I recommend cloning this template and running that locally without changing anything: https://github.com/MetaMask/template-snap-monorepo

Thank you for your help.

I was able to have the app running successfully on localhost except this error I see in logs (BTW I am on a linux environment on chromebook)

But when I try to connect I have two problems:

first one is this error message

second thing I can't scroll down to accept and go to next step

I was able to run it successfully on windows locally

Closing this since GitHub Codespaces is not something that the snaps team currently supports.
