Why is it bad practice to always return `200 OK` with an error in the body like `{"error": "not found"}`?

Question

Answer

Browsers automatically redirect when they see a 200 response with any body content

Answer

JSON format is not supported by all HTTP clients and browsers

Answer

Error responses must be in XML format according to HTTP specifications

Answer

Monitoring tools and API gateways read HTTP status codes, not body content, so they can't detect errors
