Troubleshooting

Before You Begin​

This guide is for common troubleshooting tips when developing with the @pantheon-systems/gatsby-wordpress-starter. For information on troubleshooting on Pantheon, see Pantheon Front-End Sites Frequently Asked Questions.

gatsby-source-wordpress Fails To Fetch Data From WordPress​

There are a few possible reasons for this:

  1. The WP GraphQL plugin in WordPress has not been activated

  2. The WP Gatsby plugin in WordPress has not been activated

    Solution: activate the plugin

  3. The gatsby-source-plugin fails with the following error:

    Error: getaddrinfo ENOTFOUND dev-my-wordpress-site.pantheonsite.io
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:71:26)

    Error occurred while fetching non-Node root fields.

    Solution: Check that the WordPress site it active and try the command again. Ensure both the WP GraphQL and WP Gatsby plugins are activated.

WordPress Server Overloaded​

Rarely, the gatsby-source-wordpress server complains of an overloaded WordPress server. If you are experiencing this issue frequently, it is recommended to add the following options to the gatsby-source-wordpress plugin inside of the gatsby-config.js. See the plugin options on schema request concurrency for more information.

{
// ...rest of config,
plugins: [
    resolve: `gatsby-source-wordpress`,
            options: {
                url,
                schema: {
                   perPage: 20, // default 100
                   requestConcurrency: 5, // default 15
                   previewRequestConcurrency: 2, // default 5
                 },
            },
    
    ]
}
