Problem:

When attempting to do social sign on with React Native you encounter the following error: The+value+of+%22redirectTo%22+is+not+allowed.

Given:

1. You’ve copied the example React Native template: https://www.npmjs.com/package/@nhost/react-native-template
2. You’ve followed the appropriate social sign on guide (in my case it was https://docs.nhost.io/guides/auth/social/sign-in-google )
3. You’ve updated the nhost /settings/authentication property Allowed Redirect URLs so that allowed redirects includes both your web app urls AND your mobile app URI scheme, e.g. http://localhost:3000, https://XXXX.vercel.app, myapp://

Note: You can only see this error if you’re using charles proxy or something similar since the error is happening in the request made by react-native-inappbrowser-reborn. The symptom of the error is you’ll see the in app browser open up the page you’ve specified in CLIENT_URL property in nhost /settings/authentication

Solution:

Check your Auth Version in nhost /settings/authentication. Deep link support to the redirectTo was added in v0.30.0 of hasura auth (nhost/hasura-auth#513, https://github.com/nhost/hasura-auth/releases). If you update your auth version, you should be able to specify the mobile app URI scheme in the redirect urls and not encounter an error.

NOTE: I’m new to Hasura and nhost. And I don’t have guidance on what auth version upgrades are safe or unsafe.
