Configure auth as:

],
});
Call await auth.api.setActiveOrganization
try {
console.log(org id ${userOrgs[0].id});
await auth.api.setActiveOrganization({
body: {
organizationId: userOrgs[0].id,
},
// This endpoint requires session cookies.
headers: await headers(),
});
console.log(after setActiveOrganization);
} catch (err: any) {
if (err instanceof APIError) {
const apiErr: APIError = err;
console.log(
error code ${apiErr.statusCode} error message ${apiErr.message},
);
} else {
console.log(other error ${JSON.stringify(err, null, 2)});
}
}

Current vs. Expected behavior

I expect the organizationId to be added to the sesson without error:
Error returned
other error {
"reason": "invalid-input",
"model": "Session"
}

Org id immediately before the call:
org id 7MB5idvLxFQ9UfZVckSrcki1rKxnz6vT

(Select all that apply) Backend, Client ### Auth config (if applicable) ```typescript import { betterAuth } from "better-auth" export const auth = betterAuth({ emailAndPassword: { enabled: true }, }); ``` ### Additional context I have tested against the latest release 1.5.6. It is currently local. If required i can upload to GH.

Hi @chrishj59! I'm Dosu and I’m helping the better-auth team.

The error {"reason": "invalid-input", "model": "Session"} is almost certainly coming from your ZenStack adapter, not from Better Auth itself — this error format doesn't exist in Better Auth's codebase [1].

Here's what's happening: when setActiveOrganization is called, it tries to update the session record with activeOrganizationId [2]. The organization plugin adds this field to Better Auth's internal session schema [3], but ZenStack requires you to explicitly define all fields in your .zmodel file. If activeOrganizationId isn't in your ZenStack Session model, the adapter rejects the update.

A strong clue: your session object shows activeTeamId: null but activeOrganizationId is completely absent, suggesting that column doesn't exist in your ZenStack schema/database.

Fix: Add the missing fields to your ZenStack Session model:

model Session {
  // ... your existing fields ...
  activeOrganizationId   String?  // Add this
  activeTeamId           String?  // Add this if not already present
  impersonatedBy         String?  // From admin plugin
  // ...
}

Then regenerate and migrate:

npx zenstack generate
# Run your database migration as needed

This is a common issue with custom/community adapters — they require manual schema synchronization when Better Auth plugins add new fields [4]. The built-in adapters (Prisma, Drizzle, Kysely) handle this more automatically.
