[v2] TypeError: EntitiesRepo is not a constructor

[marcammann]

I tried setting up a vanilla Gatsby v2 instance this morning and I'm getting stuck right after the configuration.

Using version gatsby-source-datocms @ 2.0.0-alpha.2 and datocms-client @ 0.5.7 (tried 0.6.0 as well)

This is the error:

success open and validate gatsby-config — 0.012 s
success load plugins — 0.255 s
success onPreInit — 0.652 s
success delete html and css files from previous builds — 0.009 s
success initialize cache — 0.017 s
success copy gatsby files — 0.044 s
success onPreBootstrap — 0.001 s
error Plugin gatsby-source-datocms returned an error

What I tracked it down to is that the default exports from datocms-client need an extra .default argument as default isn't not automatically resolved. I found some notes that Babel now doesn't automatically access the default property anymore. Even trying to set output.libraryExport in the Webpack config override didn't do the trick.

I am getting the same issue as well.

I too am getting this error with an otherwise vanilla gatsby starter. Has something changed in the plugin recently? Or is this an issue with the Dato CMS API?

  "dependencies": {
    "dotenv": "^6.0.0",
    "gatsby": "^1.9.247",
    "gatsby-link": "^1.6.40",
    "gatsby-plugin-react-helmet": "^2.0.10",
    "gatsby-source-datocms": "^1.1.11",
    "react-helmet": "^5.2.0"
  },

...

module.exports = {
  siteMetadata: {
    title: 'Gatsby Default Starter',
  },
  plugins: [
    'gatsby-plugin-react-helmet',
    {
      resolve: `gatsby-source-datocms`,
      options: {
        apiToken: process.env.DATO_API_TOKEN,
        preview: false,
        disableLiveReload: false,
      },
    },
  ],
}

We should have fixed the issue with v2.0.0-alpha.5
