When I try to load a user with this url: https://kitsu.io/api/edge/users?filter[self]=true&include=libraryEntries.media&page[limit]=10&page[offset]=0 , the server return an error 503 with big libraries. The body of the response is: <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <meta charset="utf-8"> <title>Application Error</title> <style media="screen"> html,body,iframe { margin: 0; padding: 0; } html,body { height: 100%; overflow: hidden; } iframe { width: 100%; height: 100%; border: 0; } </style> </head> <body> <iframe src=" //www.herokucdn.com/error-pages/application-error.html"></iframe> </body> </html>
