I'm creating an API route to send emails with Sendgrid, no files. I get the error on build time. I removed the API route, and the build passes, so I'm 100% sure the error is in there.

Here is the code for the route (I hid the emails, but that is not in the original code):

const sgMail = require("@sendgrid/mail");
sgMail.setApiKey(process.env.SENDGRID_API_KEY);

export const config = {
  maxDuration: 5,
};

function getSupportEmail() {
  const locale = process.env.NEXT_PUBLIC_LOCALE;
  if (locale === "en-CA" || locale === "fr-CA") {
    return "****@***.***";
  } else {
    return "****@****.***";
  }
}

export default async function formHandler(req, res) {
  const { email, name, message } = req.body;

  const msg = {
    to: getSupportEmail(),
    from: email || "",
    subject: `New Message from ${name || ""}`,
    text: message || "",
  };

  try {
    await sgMail.send(msg);
    res.json({ message: "Email sent successfully" });
  } catch (error) {
    console.error(error); // Optional: Log the error for debugging
    res.status(500).json({ error: "Failed to send email" });
  }
}
