• Monorepo: Turborepo
• Package Manager: pnpm 10.19.0
• Node.js: >= 20.10.0

amplify.yml Configuration

version: 1
applications:
  - appRoot: apps/web
    frontend:
      phases:
        preBuild:
          commands:
            - corepack enable
            - corepack prepare pnpm@latest --activate
            - pnpm install
        build:
          commands:
            - cd ../..
            - pnpm turbo run build --filter=web
      artifacts:
        baseDirectory: .next
        files:
          - "**/*"

Build completes successfully, but deployment fails with an error indicating the build artifacts cannot be found.

I can download the build artifacts in the console, and it all appears to be there, but the deploy step cant seem to find them.

[INFO]: Build Artifacts not found.
[ERROR]: {"code":"MissingBuildArtifacts"}

Describe how you'd like this feature to work

After a successful build, Amplify should find the .next directory at apps/web/.next and deploy the application.
