Describe the bug

Error in the title appears when I run netlify dev on my Gridsome project.

To Reproduce

Steps to reproduce the behavior:

1. Run git clone https://github.com/platform-kit/generator generator
2. Navigate to the cloned repository
3. Run ./bin/run seedData
4. Run gridsome develop (note that the underlying site builder works)
5. Run netlify dev
6. See that the CLI exits with the error in the title

I saw this issue too while trying to get https://github.com/netlify/netlify-faunadb-example set up after using the deploy button!

@lpatmo

I found this very frustrating to debug. No output to work off of. I ended up removing chunks of code at random until something changed. The culprit was a script in the package.json "scripts" section. Hope that helps.

@platform-kit Thanks!

I am having same issue after update to latest version (netlify-cli/2.64.1 win32-x64 node-v12.13.1),

package.json

scripts": {
    "develop": "netlify dev",
    "build": "gatsby build",
    "clean": "gatsby clean",
    "format": "prettier --write src/**/*.{js,jsx}",
    "serve": "gatsby serve",
    "test": "echo \"Write tests! -> https://gatsby.dev/unit-testing\""
  }

Thanks @Nisfan, do you mind opening a new issue for it?
