'Cannot query field "langKey" on type "fields".

Hi,

I'm trying to get gatsby-plugin-i18n to work with my blog. I keep getting this error when I run gatsby develop and I couldn't find the solution anywhere.

// my gatsby-config.js

const languages = require('./data/languages');

module.exports = {
    siteMetadata: {
        title: `My website`,
        googleVerification: `abcdefz`,
        disqus: `gatsby-typescript`,
        languages
    },
    mapping: {
        'MarkdownRemark.frontmatter.author': `AuthorJson`
    },
    plugins: [
        // Expose `/data` to graphQL layer
        {
            resolve: `gatsby-source-filesystem`,
            options: {
                name: `data`,
                path: `${__dirname}/data`
            }
        },

        {
            resolve: `gatsby-plugin-google-analytics`,
            options: {
                trackingId: 'YOUR_GOOGLE_ANALYTICS_TRACKING_ID',
                // Puts tracking script in the head instead of the body
                head: false,
                // Setting this parameter is optional
                anonymize: true,
                // Setting this parameter is also optional
                respectDNT: true
            }
        },

        // Parse all markdown files (each plugin add/parse some data into graphQL layer)
        {
            resolve: `gatsby-transformer-remark`,
            options: {
                plugins: [

                ]

        {

            options: { // Default options

        // Add typescript stack into webpack
        `gatsby-plugin-typescript`,

        // web manifest file so your website can be added to your
        // homescreen on Android.
        /* eslint-disable camelcase */
        {
            resolve: `gatsby-plugin-manifest`,
            options: {

        /* eslint-enable camelcase */

        // This plugin generates a service worker and AppShell
        // html file so the site works offline and is otherwise
        // resistant to bad networks. Works with almost any

    ]
};

Any help is appreciated. Let me know if you need to see anything else.

Just meet the same error message.

Problem come from onCreateNode which reject my blog posts for not having 'isInPagesPaths' at true. By default, pagesPaths is ['/src/pages/'].

So I "fix" this with a correct configuration (my markdowns are in content/blog) :

    {
      resolve: 'gatsby-plugin-i18n',
      options: {
        langKeyDefault: 'en',
        useLangKeyLayout: false,
        pagesPaths: [`${__dirname}/content/blog`]
      }
    }

Hello guys, I'm trying to implement yours package on my website and I'm followed the README documentation, I do that is there but I'm catching this error:

 ERROR #85901  GRAPHQL

There was an error in your GraphQL query:

Cannot query field "langKey" on type "MarkdownRemarkFields".

File: node_modules/gatsby-plugin-i18n/createPages.js:46:10

This is the source with error: https://github.com/davidcostadev/davidcosta.com.br/pull/2

Hum... I did what @Charlynux suggest and works. But I think that its need to be added on README too

Sorry for flood, but I'm getting this error now:

  Error: A plugin tried to update a node field that it doesn't own:
