Drogon does not load the database connection configuration from config.json

Hello! Drogon does not accept the connection described in config.json. I tried MySQL, sqlite3

`test_drogon: /home/insomnia/Projects/test_drogon/drogon/lib/src/DbClientManager.h:46: drogon::orm::DbClientPtr drogon::orm::DbClientManager::getDbClient(const std::string&): Assertion `dbClientsMap_.find(name) != dbClientsMap_.end()' failed.`

`// Set HTTP listener address and port
drogon::app().addListener("0.0.0.0", 5555);

// drogon::app().createDbClient(
// "mysql", "127.0.0.1", 3306, "ariadne_thread",
// "drogon_user", "RT_s20$146Zs%k", 1, "", "mk", false, "", -1, false);

// Load config file
drogon::app().loadConfigFile("../config.json");
drogon::orm::DbClientPtr db = drogon::app().getDbClient("default");
// drogon::app().loadConfigFile("../config.yaml");
// Run HTTP framework,the method will block in the internal event loop

drogon::app().run();
return 0;`

config.json
