On November 26th 2022, the HyperText Transfer Protocol (HTTP) 503 Service Unavailable error response code may appear when attempting to make a request. This is an indication that the server is currently unable to handle the request and could be due to maintenance or overload of the system.

For redirections, three hundred to three hundred and ninety nine is the range used. When there are client errors four hundred to four hundred ninety nine is applicable and server errors have a five hundred to five hundred and ninety-nine range.
What is a 504 status code?
When CloudFront passes on a request to the origin because the requested item isn’t in the edge cache, an HTTP 504 status code (Gateway Timeout) may be returned. This is when either the origin sends back an HTTP 504 status code of its own or it does not respond before the request expires.
How do I validate a REST API?
Open UserResource.java and add the @Valid annotation.
In User.java, add the @Size(min=5) annotation above the name variable.
Below that, also add an @Past annotation above the dob variable.
If there are any other fields present in this resource that need to be validated, apply annotations accordingly as a further step in implementing validations for RESTful services.
