Hi everyone,

I’m troubleshooting some recurring 500 Internal Server Errors in a Node.js/Express app. Most of them happen during API requests, and the logs don’t always provide a helpful stack trace. I’ve reviewed route logic, middleware functions, and database interactions, but the issue still pops up sporadically.

Are there typical causes or overlooked areas in Express apps that could lead to this? I’ve seen mentions of unhandled promises and async errors, but I’d appreciate any real-world examples.

While going through general practices followed by a web development agency, I noticed structured error-handling patterns being emphasized. Curious if anyone else uses something similar that’s worked well in production.

Would love to hear your thoughts or approaches that have helped you resolve this in your own projects.
