phoneNumber plugin not working with expoClient - session returns null
Hi, I'm trying to use the phoneNumber plugin with Expo/React Native and can't get sessions to work after OTP verification.
Setup:
- better-auth v1.4.17
- @better-auth/expo v1.4.17
- Expo SDK 55
- React Native 0.83.1
- Hono trpc
Server config:
getTempName: (phone) => phone,
},
}),
],
session: {
modelName: "MarketplaceSession",
cookieCache: { enabled: true, maxAge: 60 },
},
});
Mobile client config:
export const authClient = createAuthClient({
baseURL: getApiBaseUrl(),
plugins: [
expoClient({
scheme: "loopearn",
storagePrefix: "loopearn",
storage: SecureStore,
}),
],
});
Issue:
phoneNumber.verify() succeeds ✓
Server sends signed cookie in Set-Cookie header: token.signature ✓
Response body has unsigned token ✓
But subsequent get-session calls return null (401) ✗
Server logs show:
verify response has Set-Cookie: loopearn-auth.session_token=ABC123.SIGNATURE
But mobile only gets unsigned token: ABC123
Question: How should phoneNumber plugin work with expoClient in React Native? Should the signed cookie be captured automatically, or do I need to manually handle the token from the response body? Is phoneNumber + expo a supported combination?
