Hello, @steffen-tomm 👋. Did you recently upgrade your app from v5 to v6 by chance, or is this a new v6 app? And can you share what's in your package.json file so we can see your dependencies?

[cwomack]

Additionally, can you see if taking the following steps helps resolve the issue?

• Delete your node_modules folder
• Delete your package-lock.json file
• Reinstall dependencies with npm i

[steffen-tomm]

@cwomack i tried that already, good advise so far.

started directly with v6, like in that documentation:
https://docs.amplify.aws/nextjs/start/project-setup/create-application/

package.json looks like that:

{
  "name": "test",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "next lint"
  },
  "dependencies": {
    "@aws-amplify/adapter-nextjs": "^1.0.28",
    "aws-amplify": "^6.0.28",
    "classnames": "^2.5.1",
    "next": "^14.2.1",
    "react": "^18.2.0",
    "react-dom": "^18.2.0"
  },
  "devDependencies": {
    "@svgr/webpack": "^8.1.0",
    "@types/node": "^20",
    "@types/react": "^18",
    "@types/react-dom": "^18",
    "autoprefixer": "^10.4.19",

  }
}

import {type ResourcesConfig} from 'aws-amplify';

export const authConfig: ResourcesConfig['Auth'] = {
    Cognito: {
        userPoolId: 'eu-central-1_SSt3fgGcD',
        userPoolClientId: '5sdfs8fsafdsdvdsafsq2gphi5dsfs',
        identityPoolId: 'eu-central-1:023450d4-dfa43-123a-4533-dfsafdssa543,
        allowGuestAccess: true,
    }
};

export const apiConfig: ResourcesConfig['API'] = {
    GraphQL: {
        endpoint: 'https://dsfgafa4ew5w4xdgfd.appsync-api.eu-central-1.amazonaws.com/graphql',
        region: 'eu-central-1', // optional
        defaultAuthMode: 'userPool'
    }
};

that's my config. is something wrong here?

@steffen-tomm, I'm still a little lost as to how to reproduce this issue and get the errors you're seeing. You mentioned starting with the Next.JS getting started guide, but can you share the steps that different from our docs to get to where you're experiencing the build issues? Do you run into this with a fresh Next.JS project with Amplify imported or was this an existing project that you integrated Amplify into? And finally, do you experience this when running it locally as well?

[steffen-tomm]

i started building the project two month ago, but never went through the build process, because i always ran
npm run dev
without any issues.
