When Horizon can’t find whatever you are requesting, it will return a not_found error. This is similar to a “۴۰۴ Not Found” error response in HTTP.
Incorrect URL path parameters or missing data are the common reasons for this error. If you navigate using a link from a valid response, you should never receive this error message.
As with all errors Horizon returns, not_found follows the Problem Details for HTTP APIs draft specification guide and thus has the following attributes:
|The identifier for the error. This is a URL that can be visited in the browser
|A short title describing the error
|An HTTP status code that maps to the error
|A more detailed description of the error
|A token that uniquely identifies this request. Allows server administrators to correlate a client report with server log files
