404.js is here.

import { Link } from "gatsby";
import * as React from "react";
import Layout from "../layouts";
import { default as Seo } from "../layouts/head";

const NotFoundPage = () => {
  return (
    <Layout>
      <Link to="/">Go home</Link>.
    </Layout>

};

export default NotFoundPage;

export const Head = () => <Seo title="home page" />;

Here is the information on the 404 page that will be created after the build.

When I comment out gatsby-plugin-google-gtag in gatsby-config.js and then build, it passes without problems, so I think the problem is in gatsby-plugin-google-gtag, but I cannot figure out the cause.

If you need any other information, please let me know.

CodePudding user response：

You have a typo in the configuration for your gatsby-plugin-google-gtag plugin: trackingId should be trackingIds (note the trailing S)

{
  resolve: "gatsby-plugin-google-gtag",
  options: {
    trackingIds: [process.env.GATSBY_GA_MEASUREMENT_ID],
    gtagConfig: {
      optimize_id: [process.env.GATSBY_GTM_ID],
      anonymize_ip: true,
      cookie_expires: 0,
    },
    pluginConfig: {
      head: true,
    },
  },
},
