[bug\_fix] ELIFECYCLE Exit status 1

Scroll up in the terminal output past the npm error block to find the actual underlying tool error \(e.g., Webpack compilation error, TypeScript type error, or missing test assertion\). Fix the underlying code or configuration issue causing the script to exit non-zero.

Journey Context:
A developer runs npm run build which executes webpack --mode production. Webpack encounters a syntax error in src/components/App.js \(an unexpected token or missing import\). Webpack's compiler emits an error message and the process exits with code 1. npm captures this exit code and wraps it in its own error reporting: 'npm ERR\! code ELIFECYCLE', 'npm ERR\! errno 1', 'npm ERR\! [email protected] build: webpack', 'npm ERR\! Exit status 1'. The developer panics upon seeing the npm error block at the bottom of the terminal, thinking npm itself is broken or the package.json is malformed. They try deleting node\_modules and reinstalling, which doesn't help. Eventually, they scroll up past the npm error traceback and find the actual Webpack error message showing the specific file and line number with the syntax error. They fix the code, and the ELIFECYCLE error disappears because the underlying tool no longer exits with an error.
