not_found

HTTP 404 · code not_found

No route matches the path, or the resource does not exist.

When Photon sends it

Sent by the router when no route matches (unless you set a custom NotFound handler), and by handlers through photonerr.NotFound(what), whose message is “what not found”.

What the client should do

Check the URL and the resource identifier.

Example response

{
  "type": "https://photon.agenticmarket.dev/errors/not_found",
  "title": "not found",
  "status": 404,
  "code": "not_found"
}

Match on the code field rather than on title, which is meant for people and may change. See all error codes.
