I will fix node js and typescript bugs in your vibe coded app

I will fix one clearly defined bug in an existing JavaScript, TypeScript, or Node.js project. Typical jobs include build errors, runtime exceptions, broken API requests, validation problems, and small logic defects.

You will receive focused code changes, basic error handling, and concise verification notes. If the project already has a working test setup, I will add or update one relevant test where practical.

This Gig covers one reproducible issue in up to 4 source, config, or test files and approximately 200 changed lines. It does not cover a new application, full feature, UI redesign, database migration, payment or authentication architecture, production deployment, emergency server recovery, or multiple unrelated bugs.

Please send the exact error, reproduction steps, expected result, runtime versions, and only the relevant source files. Remove .env files, passwords, API keys, private keys, and personal or customer data. I work with public documentation, mock data, test mode where available, and environment variable placeholders.
