[SOLVED] Your wordpress server appears to be overloaded. [Gatsby]

Your wordpress server appears to be overloaded. [Gatsby]

I'm getting the error below when trying to call gatsby develop.

 ERROR #gatsby-source-wordpress-experimental_111007 

 gatsby-source-wordpress  Your wordpress server at http://localwp/graphql appears to be overloaded.

Try reducing the requestConcurrency for content updates or the previewRequestConcurrency for previews:

{
  resolve: 'gatsby-source-wordpress-experimental',
  options: {
    schema: {
      requestConcurrency: 5, // currently set to 5
      previewRequestConcurrency: 2, // currently set to 2
    }
  },
}

The GATSBY_CONCURRENT_REQUEST environment variable is no longer used to control concurrency.
If you were previously using that, you'll need to use the settings above instead.

I tried to set requestConcurrency: 5 and previewRequestConcurrency: 2 as suggested but it was not enough.

Things I did before getting error appeared that may be related:

I updated the WPGraphQL plugin (v1.1.1) today (I tried to downgrade to v1.1.0 but the problem persists)
I set useGatsbyImage (within the 'gatsby-source-wordpress-experimental' options in gatsby-config.js) to false to do some tests.

Plugins used on Wordpress are: WP Gatsby (v0.9.1), WP GraphQL (v1.1.0), WP GraphQL Gutenberg (v0.3.5).

I'm running a local wordpress server (via Local) and it seems to be working normally.

Appreciate any help!

Solution

[SOLVED] : I disabled WP GraphQL Gutenberg (v0.3.5) and it started to work again. Looks like this plugin might be overloading the wordpress server. It's probably some incompatibility between WP GraphQL (v1.1.0) and WP GraphQL Gutenberg (v0.3.5). More information about this incompatibility here.
