Whitelist config for local environment in expo

Can someone clarify what should the config look like for whitelisting in local environment.

Scheme in app.json: caa

Tried putting caa://auth, but it’s still throwing error. It works if I put exp://, but we work in a team, doesn’t that mean every one of us has to change it every time they are testing.


When you’re running your app in expo’s local environment, expo creates a server in your local system which is referenced by your mobile apps. Hence the whitelist URL at that point must be the system IP. Your published app however takes the scheme in the app.json.

Hence, for testing purposes, you’ll have to ask your developers to manually whitelist the IPs of their system in the local network. As long as their IPs are the same, they’ll be able to access the app.
