Debug a Build Failure

When debugging a build failure:

1. Read the build error output from the top. The first error is usually the root cause — later errors are often cascading.
2. Identify the file and line referenced in the error.
3. Check for common causes: missing imports, type mismatches, syntax errors, incompatible dependency versions.
4. If the build worked recently, check what changed: git diff or recent commits.
5. Try a clean build: delete the build cache, node_modules (if applicable), and rebuild from scratch.
6. If a dependency update caused the failure, check the dependency’s changelog for breaking changes.
7. Fix the root cause. Don’t suppress warnings or errors with overrides unless you understand the implications.
