Better Auth + Convex Integration Issue: Users Not Persisting to Database

Convex + Better Auth Integration Issue (React Native/Expo) Environment: - React Native/Expo app - better-auth@1.3.23, @better-auth/expo@1.3.23, @convex-dev/better-auth@0.8.6, convex@1.27.3 (all latest) Problem: Authentication works (signup, signin, tokens generated) but users are NOT persisted to Convex database. Better Auth appears to use in-memory storage fallback. Setup (following official docs): ✅ convex.config.ts with Better Auth component ✅ auth.config.ts configured ✅ convex/auth.ts with authComponent.adapter(ctx) ✅ HTTP routes via authComponent.registerRoutes() ✅ Environment variables (BETTER_AUTH_SECRET, CONVEX_SITE_URL, EXPO_PUBLIC_CONVEX_SITE_URL) ✅ Schema includes all tables (user, account, session, verification) ✅ Direct Convex mutations work What happens: 1. User signs up via /api/auth/sign-up/email 2. Better Auth returns success with user ID/token 3. User can sign in successfully 4. BUT: Convex tables remain empty (verified via dashboard) 5. Better Auth recognizes returning users ("existing email") without database persistence Code:

// convex/auth.ts
export const authComponent = createClient<DataModel>(components.betterAuth);
export const createAuth = (ctx: GenericCtx<DataModel>, { optionsOnly } = { optionsOnly: false }) => {
  return betterAuth({
    baseURL: process.env.SITE_URL,
    trustedOrigins: ["edgame://"],
    database: authComponent.adapter(ctx),
    emailAndPassword: { enabled: true, requireEmailVerification: false },
    plugins: [expo(), convex()],
  });
};

// convex/http.ts
authComponent.registerRoutes(http, createAuth);

// convex/auth.ts
export const authComponent = createClient<DataModel>(components.betterAuth);
export const createAuth = (ctx: GenericCtx<DataModel>, { optionsOnly } = { optionsOnly: false }) => {
  return betterAuth({
    baseURL: process.env.SITE_URL,
    trustedOrigins: ["edgame://"],
    database: authComponent.adapter(ctx),
    emailAndPassword: { enabled: true, requireEmailVerification: false },
    plugins: [expo(), convex()],
  });
};

// convex/http.ts
authComponent.registerRoutes(http, createAuth);

Confirmed: - Adapter never called for DB operations - Sessions work only until restart (in-memory) - Direct Convex writes work fine Question: Is this a known React Native/Expo integration issue? The adapter isn't being called. Any specific RN/Expo configuration needed? This makes the integration unusable for production apps. cc: @Wayne

@SacredGamer hi can you ask in the #better-auth channel?

Data is being persisted, you're looking at the app tables. Components have their own tables. When you're looking at the data view in the dashboard, there's a dropdown in the top left where you can select "betterAuth" to see auth tables.
