PLEASE help us help you by writing a good post!

  • we need to know your netlify site name. Example: cheery-dasik-2ee03b.netlify.app
  • DNS issues? Tell us the custom domain, tell us the error message! We can’t help if we don’t know your domain.
  • Build problems? Link or paste the FULL build log & build settings screenshot

The better the post - the faster the answer.

This is the Error code :

I have changed build to

“build”: “CI= npm run build”,

This was the result

10:34:15 PM: > webapp@0.2.0 build

I have changed the files to
netlify.toml

and


[build]
  command = "npm run build && node ./sayHello.js"

This was the result

@70ny npm run build runs the build script in your package.json, what is in your package.json?

Here is the git file

@70ny It looks like you’ve been duplicating the command that should be your Netlify Build command (either in the settings or the netlify.toml as you’ve shown), into your package.json build script.

You don’t want to do this, it’ll cause an infinite loop as per one of the logs supplied above.

It would look like this:

  1. The initial execution from the netlify.toml command runs npm run build
  2. npm run build executes the build script in the package.json which runs npm run build
  3. npm run build executes the build script in the package.json which runs npm run build
  4. npm run build executes the build script in the package.json which runs npm run build
    … etc

Based on your other package.json scripts executing react-scripts you almost certainly want to change the build one back to what it would have been originally:

"scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",

That way when npm run build is executed via the netlify.toml it runs react-scripts build.
