Description

Build app fails running "appkit-react-native-develop/apps/native$ npx expo start"
on web. The error in the Visual Studio Code console is the following : "Error bad request. Missing one of the following required values: userAgent, ip, domain or bundledId". The app does not able to connect to metamask browser extension.
On android "appkit-react-native-develop/apps/native$ npx expo start" works fine.
Thanks in advance for any tips!

AppKit SDK version

@reown/appkit-wagmi-react-native@2.0.1

Output of npx react-native info

"devDependencies": {
"@react-native-community/cli": "latest",
}

Expo Version (if applies)

"expo": "^52.0.38"

hey @luisannacocco 👋 im not sure why are you following the docs to run the project locally?

https://github.com/reown-com/appkit-react-native/blob/develop/.github/docs/development.md

Use yarn to install the dependencies and run the project. Also, this SDK is meant to be used on mobile, it doesn't support browser extensions

Hi Ignacio, Thanks for your reply! I'm not an expert in this field, I read the article by Thiago Brezinski https://www.callstack.com/blog/cross-platform-web3-dapps-with-react-native and I was wondering if starting from the project "reown-com/appkit-react-native" I could modify it to run it on the web too. Thanks in advance for any advice Luisanna Il Lun 29 Dic 2025, 16:34 Ignacio Santise ***@***.***> ha scritto:

@luisannacocco got it! Thiago's post is based on an old version of appkit, you can follow our docs here for the latest instructions: https://docs.reown.com/appkit/react-native/core/installation

The SDK works for web, but its limited and we don't actively work on it as we focus on mobile. But the basic stuff should work well.

You shouldn't have that error, check our install steps and try again 🙏
