Symptom

Build failures can occur when attempting to deploy an application to Launch from a monorepo setup. The deployment fails during the build phase, preventing the application from going live.

Root Cause

Build failures in monorepos are often caused by missing shared dependencies in the configuration files or an incorrectly formatted build command that fails to target the specific project folder.

Resolution

1. Ensure the build command correctly targets the intended project folder using the appropriate filter flags.
2. Identify if any storefront files import logic from shared internal packages.
3. Add any missing internal shared packages to the project's dependency list.

Verification

Check the Deployment Logs in the Launch dashboard for the new build attempt. If the build completes successfully and the "Deployment Succeeded" message appears, the issue is resolved.

Symptom

A deployment may succeed in one environment (such as Development) but fail in another (such as Staging) using the same code branch. These discrepancies often prevent specific environments from reflecting the latest updates.

Root Cause

Environment-specific build failures are frequently caused by improperly formatted environment variables, such as values containing unnecessary quotation marks or stray spaces that the build process cannot parse correctly.

Resolution

Inspect environment variable values for formatting errors. Remove any enclosing quotation marks or unnecessary spaces from the variable strings.

Verification

Monitor the build status of the Staging environment in the Launch dashboard. If the deployment completes successfully after the formatting changes, the issue is resolved.
