Solutions

1. Complete the Basecamp 3 OAuth connect flow first so a credential row is created.
2. Verify a credential row exists for the user before exposing the project mutation UI.
3. Re-install the Basecamp 3 app if it was removed.

const credential = await prisma.credential.findFirst({
  where: { userId },
  select: credentialForCalendarServiceSelect,
});
if (!credential) {
  // hide the project mutation UI; prompt the user to connect Basecamp first
}

When it happens

Trigger: User opened the Basecamp settings before completing the OAuth connect step; the credential was deleted; the request is for a different user account that never connected Basecamp.

Common situations: User skipped the connect step; uninstall removed the credential; multiple accounts and the active one lacks the credential.
