I'm attempting to deploy a Next.js site in a Turborepo monorepo to an Azure Static Web App using GitHub actions and a custom build step. The Next.js site is configured to use a standalone output, but otherwise follows preset configurations. The deployment job is failing with the following error:
Failed to find a default file in the app artifacts folder (apps/web/.next). Valid default files: index.html,Index.html.
If your application contains purely static content, please verify that the variable 'app_location' in your workflow file points to the root of your application.
The build and deploy job configuration is as follows:
build_and_deploy_job:
if: github.event_name == 'push' || (github.event_name == 'pull_request' && github.event.action != 'closed')
runs-on: ubuntu-latest
name: Build and Deploy Job
steps:
- uses: actions/checkout@v3
with:
submodules: true
- run: |
npm install turbo -g
npm i
turbo run build --filter=web
cp apps/web/staticwebapp.config.json apps/web/.next
- name: Build And Deploy
id: builddeploy
uses: Azure/static-web-apps-deploy@v1
with:
azure_static_web_apps_api_token: ${{ secrets.AZURE_STATIC_WEB_APPS_API_TOKEN_HAPPY_WAVE_0A47E7A0F }}
repo_token: ${{ secrets.GITHUB_TOKEN }}
action: "upload"
skip_app_build: true
app_location: "apps/web/.next"
api_location: ""
output_location: ""
What configuration or additional steps are required to deploy a Next.js app in a Turborepo monorepo to an Azure static web app? I confirmed that the same app outside of the monorepo context can be successfully deployed, but this was able to be done without a custom build step.
