Error about Prisma in Remix's Jokes App tutorial

Question

In Remix's Jokes App tutorial, I got an error in the process of getting a user in session.server.ts.

I think the error is about Prisma, but I don't know how to solve it.

TypeError: Cannot read properties of undefined (reading 'findUnique')

It seems to occur in the findUnique call in the following code.

export async function login({
  username,
  password
}: LoginForm) {
  const user = await db.user.findUnique({
    where: { username }
  });
  if (!user) return null;

  const isCorrectPassword = await bcrypt.compare(
    password,
    user.passwordHash
  );
  if (!isCorrectPassword) return null;

  return user;
}

I restarted the Docker container and that solved the problem. Thank you.
