What Is HTTP 500 Internal Server Error?

HTTP 500 Internal Server Error explained, and what it means when you see it in CI/CD and deployments.

HTTP 500 is a generic server-side error indicating something went wrong on the server.

What it means

A 500 means the request was fine but the server failed to handle it, often due to an unhandled exception. It is a server problem, not a client one.

When you see it in CI/CD

In CI, a 500 from your own service during a deploy test points to an application bug. A 500 from a third-party API may be transient; a short retry is reasonable, but persistent 500s need investigation.

Key takeaways

• 500 is a generic server error.
• Your service: likely a bug.
• Third-party: may be transient.
