Syntax Error Fix & Website Maintenance

Up until now, my site has been working without any problems. When I try to run it using ‘npm start’, I encounter a syntax error in the backend code. Since I lack the technical knowledge to fix this problem, I am asking for your help to fix the error and manage the maintenance of the site.

Here is the link to the Github repository: https://github.com/ProjectWebWizard/NodeJS
Try running it and see what's wrong

If the first project goes well, I am willing to discuss a long-term co-operation.

Ideal skills and experience:
- Knowledge of JavaScript and Node.js
- Strong understanding of backend development
- Experience troubleshooting and fixing syntax errors
- Knowledge of website maintenance
- Good communication skills for regular updates
