"gatsby-source-wordpress" threw an error while running the sourceNodes lifecycle while deploying to Netlify

[andrewgilliland]

Description

I am seeing the error ""gatsby-source-wordpress" threw an error while running the sourceNodes lifecycle", "Cannot read property 'data' of undefined" when I deploy to Netlify. I had looked through a previous issue that was similar, but none of the suggestions fixed this issue.

Steps to reproduce

I am using Local by Flywheel to host my wordpress locally at the url "http://headless.local/". It is pulling in the data into my Gatsby site locally at the url "http://localhost:8000/" on the gatsby develop command and it properly builds on the that gatsby build command.

This is my gatsby-config.js

module.exports = {
  siteMetadata: {
    title: `WordPress + Gatsby`,
    description: `Headless wordpress plus Gatsby.`,
    author: `@andy_gilliland`,
  },
  plugins: [
    `gatsby-plugin-netlify`,
    {
      resolve: `gatsby-source-wordpress`,
      options: {
        baseUrl: `headless.local/`,
        protocol: `http`,
        hostingWPCOM: false,
        useACF: true,
      },
    },
    `gatsby-plugin-react-helmet`,
    {
      resolve: `gatsby-source-filesystem`,
      options: {
        name: `images`,
        path: `${__dirname}/src/images`,
      },
    },
    `gatsby-transformer-sharp`,
    `gatsby-plugin-sharp`,
    {
      resolve: `gatsby-plugin-manifest`,
      options: {
        name: `gatsby-starter-default`,
        short_name: `starter`,
        start_url: `/`,
        background_color: `#663399`,
        theme_color: `#663399`,
        display: `minimal-ui`,
        icon: `src/images/gatsby-icon.png`, // This path is relative to the root of the site.
      },
    },
    // this (optional) plugin enables Progressive Web App + Offline functionality
    // To learn more, visit: https://gatsby.dev/offline
    // `gatsby-plugin-offline`,
  ],
}

Expected result

It should deploy to Netlify.

Actual result

This was the point in the Netlify deploy log where the error occurred.

Most likely that Netlify is trying to reach your local site which is not available from their servers (well, because it is local). You should probably have your wordpress site deployed somewhere first and then use it in your worpdpress-source-config for production mode. Have you tried it?

I may be completely missing something here though.

I have not tried it, but I will. Thanks for the help!
