Mocking a session works and then clears

[JasonSimms]

I want to set a mock session based on a process.env. It works at first and then is cleared. I think the library is calling the handlers route and not getting a wanted response but I can't find a code sample to bypass this.

//providers.tsx
'use client';

import { SessionProvider } from 'next-auth/react';
interface ProvidersProps {
  children: React.ReactNode;
}

const mockSession = {
  expires: new Date(Date.now() + 2 * 86400).toISOString(),
  user: { name: 'Newman' },
};

export default function Providers({ children }: ProvidersProps) {
  const shouldMock: boolean = process.env.NEXT_PUBLIC_MOCK_AUTH === 'true';

  return (
    <SessionProvider
      session={shouldMock ? mockSession : undefined}
      refetchInterval={5 * 60}
      refetchOnWindowFocus={false}
    >
      {children}
    </SessionProvider>
  );
}
