Azure App Service is a service used to create and deploy scalable, mission-critical web apps.
The error indicates that the deployment environment is building the app in a way that doesn’t correctly include or resolve all workspace packages in the pnpm monorepo. On Azure App Service, this typically happens when using ZIP or package-based deployment and the build output or package structure doesn’t match what the platform expects.
To make the workspace packages resolve correctly on Azure App Service:
- Build the app before packaging
- Run the full build locally or in CI (for example with Turborepo) so that the deployable output contains all necessary files.
- For Node.js apps, ensure all
npm/pnpmbuild steps are completed and the final output is self-contained. - When creating the ZIP package for deployment, include only the built output and required runtime files, not the raw monorepo source.
- Create a valid ZIP package for App Service
- From the root of the built app (the folder that contains the entry file such as
index.jsor the built web assets), create a ZIP without nesting an extra top-level folder. - For example:
zip -r app.zip . - Ensure that the ZIP structure matches what App Service expects: the entry point and
package.json(if needed) are at the root of the ZIP, not inside additional nested directories.
- From the root of the built app (the folder that contains the entry file such as
- Avoid unsupported package layouts
- If using a build system that produces nested or MSBuild-style packages, adjust it to output a folder-based structure that can be zipped directly.
- If the package format is incompatible with ZIP deploy, use the Azure App Service deploy task with Web Deploy or restructure the build to produce a flat folder output.
- Use Azure Pipelines deployment tasks correctly (if using CI/CD)
- In Azure Pipelines, ensure the build stage publishes the correct artifact (the built app folder or ZIP) and the release/deploy stage points to that artifact.
- If using
AzureWebApp@1orAzureRmWebAppDeployment, set thepackageinput to the correct path of the built app.
- Troubleshoot dependency issues
- If the build fails due to dependency resolution, inspect the Node/npm output logs to identify malformed
package.jsonor incompatible packages. - Fix any
package.jsonissues locally, rebuild, and redeploy.
- If the build fails due to dependency resolution, inspect the Node/npm output logs to identify malformed
These steps ensure that the deployed package contains a consistent, self-contained build where pnpm workspace packages are already resolved, avoiding runtime workspace resolution errors on Azure App Service.
