I’m not sure those two errors actually have the same cause.

@danhowitt i hope the error you’re getting is fixed in gatsby@2.13.45.

@lalmachado something in your project expects a File type to be in the schema but it isn’t. You can try either adding gatsby-source-filesystem to your project, which will add the File type (when there’s at least one file present); or try the createTypes action to manually add a File type (hard to say if/how this would work without more info)

important note for gatsby-source-graphql (and in case it is not enough to install the plugin for you):

I also had to put – unlike at other source plugins – in the gatsby-config.js for the plugin (gatsby-source-filesystem) the config snippet

NOTE: The path must be a valid path but it doesn’t have to contain any files, an empty folder works too.

Here’s an example config for the plugin:

    {
      resolve: `gatsby-source-filesystem`,
      options: {
        name: `images`,
        path: `${__dirname}/src/assets/img`,
      },
    },

This could’ve saved me a lot of time, hope it helps somebody! 😃
