[kayluhb]

Just switched to yarn and it's working.

pnpm was working with a previous version.

[mkupiniak]

I'm using yarn and it's not working, same error.

Yarn 1.x.x, macOS, zsh, @shopify/cli/3.83.1 darwin-arm64 node-v22.17.0.

Edit: Worked when I created a new app and only then a new extension. It was not working with the old app.

[0zd0]

The same applies to the latest version and pnpm

[vfonic]

I just tried shopify app generate extension => JavaScript and got the same error.

The project is Ruby on Rails app with yarn package manager. Seems like app extension generator adds new package.json inside extension dir.

Here are the contents of generated `package.json`

{
  "name": "my-extension-name",
  "version": "0.0.1",
  "license": "UNLICENSED",
  "scripts": {
    "shopify": "npm exec -- shopify",
    "typegen": "npm exec -- shopify app function typegen",
    "build": "npm exec -- shopify app function build",
    "preview": "npm exec -- shopify app function run",
    "test": "vitest"
  },
  "codegen": {
    "schema": "schema.graphql",
    "documents": "src/*.graphql",
    "generates": {
      "./generated/api.ts": {
        "plugins": [
          "typescript",
          "typescript-operations"
        ]
      }
    },
    "config": {
      "omitOperationSuffix": true
    }
  },
  "dependencies": {
    "@shopify/shopify_function": "2.0.0"
  },
  "devDependencies": {
   "vitest": "2.1.9"
  }
}

The issue could be because CLI assumes that everyone has graphql-code-generator package installed. Maybe it would be better if this is added as a dependency, either to the above package.json or to Shopify CLI itself?

[vfonic]

Seems like graphql-code-generator has been renamed to @graphql-codegen/cli? https://github.com/dotansimha/graphql-code-generator?tab=readme-ov-file#quick-start

And the new command seems to be graphql-codegen as opposed to graphql-code-generator.

I'm not 100% sure on this. Someone who added or is maintaining this functionality in Shopify CLI should have a look.

[vfonic]

I also tried:

yarn create @shopify/app
cd new-app
shopify app generate extension

and got the same error.

> shopify version

engine-strict=true
auto-install-peers=true
shamefully-hoist=true

This has been broken for more than 2 months now. Can someone please have a look? @isaacroldan ?

[vfonic]

Seems like the error comes from this line of code: https://github.com/Shopify/cli/blob/bc73a2670a973a55ebe527cba12172dbadd2ef0e/packages/app/src/cli/services/function/build.ts#L134

Here are some other relevant issues I've found:

• #3111
• #4653
• #2095
• #2031

[AshEastham-idhl]

Getting the same issue but for Javascript instead of Typescript. Checked and node/npm/cli are all on latest and also tried using pnpm instead of npm but run into the same error.

[isaacroldan]

I'll pass this to the functions team to investigate

[nicklozon]

Using shopify app init to generate an "extension only" app and shopify app init --template=ruby both generate a barebones package.json with no dependencies in the root directory.

Adding @shopify/api-codegen-preset as a devDependency fixes the issue for me.

  "devDependencies": {
    "@shopify/api-codegen-preset": "^1.1.1"
  },

[TemurbekRuziyev]

This issue is still happening, tried with the latest CLI versions: "@shopify/cli": "^3.84.0" and "@shopify/cli": "^3.85.5" using yarn 1.22.19 version

Error: Error coming from npm exec -- graphql-code-generator --config package.json Command failed with exit code 1: npm exec -- graphql-code-generator --config package.json Cannot convert undefined or null to object Parse configuration [started] Parse configuration [failed] Cannot convert undefined or null to object

EDIT: It worked after I added this library to the root package.json "@shopify/api-codegen-preset": "^1.2.0"

[sameerxanand]

Same issue with me, but works after adding @shopify/api-codegen-preset to root.
