const registerUser = async (

  try {
    const validatedData = registerSchema.parse(formData);
    console.log("Parsed form data");
    console.log(formData);

    const user = await prisma.user.findUnique({
      where: {
        email: formData.email,

    if (user) {
      console.log("User already exists");
      return {

        message: "User already exists",

    } else {
      await prisma.user.create({
        data: {
          firstName: validatedData.firstName,
          lastName: validatedData.lastName,
          email: validatedData.email,
          role: "ADMIN",

      });

      console.log("Created new user");
    }

    await signIn("resend", formData);
    console.log("Login link was sent");

    return {
      success: true,
      message: "User registered successfully",
    };
  }  catch (error) {
...
}

This is the code that causes all the erors:

await signIn("resend", formData)
