Gatsby: [gatsby-source-filesystem] pluging breaks building schema step

[jepek]

Description

After adding gatsby-source-filesystem:

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

to the gatsby-config.js Gatsby develop & build break. Error:

  Error: File.publicURL provided incorrect OutputType: 'String'

Steps to reproduce

I can't reproduce it on a clean repository. It happens only in a workspace which is a part of a bigger monorepo. I would like to debug what causes the problem.

Expected result

Adding gatsby-source-filesystem shouldn't break building schema step

Actual result

building schema step ends with an error:

success open and validate gatsby-configs - 0.035s
success load plugins - 0.528s
success onPreInit - 0.004s

My best guess would be that you have two versions of the graphql package in your repo somehow. But I may be wrong.

I am happy to help to debug this but it is rather hard without at least some reproduction.

you can remove the node_modules dir, and re run npm install/ yarn install. and the problem will be solved

[tomwanderer]

Have you installed?: npm install --save gatsby-source-filesystem

I've just recently encountered this issue and it turned out that I forgot to install the plugin first.

[jepek]

@RichardStark tried multiple times, did not help
@tomwanderer yes, gatsby-source-filesystem is installed in a project

[orifmilod]

@jepek Have you fixed this issue? I am facing the same problem at the moment.

[jepek]

@orifmilod Only by a workaround - keeping the project out of workspaces. Do you use yarn workspaces as well?

[saadnoor]

I am also facing the same issue. No luck with the above solutions.

[orifmilod]

@jepek No, I use npm. I had problems with conflicts with AWS-appsync. which was then fixed by just uninstalling the package and reinstalling it, maybe there was a bug in the older version, not sure tho.

[zhangaoyun]

I delete the node_modules directory of this project, and run npm install.
It works for me.

[Mrazator]

I have the same problem. My setup is: yarn link gatsby-theme-xyz, yarn install and gatsby build then fails with this error. Could this be connected to the yarn link? Problem with themes?

EDIT: I just published my theme to npm and the problem disappeared. It has to be something with the yarn link or workspaces...
