In error cases, the API returns an HTTP Problem JSON object with the application/problem+json media type. For example, when you try to GET a site that does not exist, the API responds with a JSON object similar to the example below:
{
"type" : "https://akzz-xxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxx.luna.akamaiapis.net/api/lcdn-services/errors#core.entity-not-found",
"title" : "The requested entity could not be found",
"detail" : "Site 99999 does not exist",
"instance" : "https://akzz-xxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxx.luna.akamaiapis.net/api/lcdn-services/v1/sites/99999#fae1fd860940d25d",
"entityType" : "Node",
"entityId" : 99999
}
