Urgent: Troubleshooting Node.js Website Issues

My website was functioning perfectly until today, when it suddenly stopped responding to 'npm start'. I am unsure of the nature of the problem, but I do know that error messages are being generated when I attempt to run the site. I need a skilled professional to troubleshoot and resolve the issue as soon as possible. Ideal skills and experience for this job include:

- Proficient in Node.js and npm
- Experience in troubleshooting web applications
- Excellent problem-solving skills
- Prior experience in website maintenance

If the issue gets resolved, I'm open to a long-term collaboration for site maintenance. Please contact me in private messages to get access to the code.
