Estou tentando conectar o cygnus (1.4.0_SNAPSHOT) ao cartodb. Eu o executo localmente e uso um script para enviar uma notificação ao cygnus. O script roda Ok, mas o cygnus diz:

ERROR sinks.NGSISink: Persistence error (The query 'INSERT INTO jcarneroatos.x002fpeoplelocation (recvtime,fiwareservicepath,entityid,entitytype,the_geom) VALUES ('2016-10-31T19:04:00.994Z','/peoplelocation','Person:1','Person',ST_SetSRID(ST_MakePoint({"coordinates":[-4.423032856,36.721290055]), 4326))' could not be executed. CartoDB response: 400 Bad Request)

Alguém sabe o que poderia estar acontecendo? Abaixo coloquei meus arquivos de configuração para obter informações, obrigado!

Meu nome de usuário na CARTO é "jcarneroatos" e o domínio éhttps://jcarneroatos.carto.com. Este é o script que estou usando para simular a notificação do Orion Context Broker:

#/bin/bash
HOST=localhost
PORT=5050
SERVICE=jcarneroatos
SUBSERVICE=/peoplelocation

#send notification
NOTIFICATION=$(\

Esta é a estrutura do conjunto de dados no cartodb:

x002fpeoplelocation
cartodb_id | the_geom | entityid | entitytype | fiwareservicepath | recvtime
  number   | geometry |  string  |   string   |      string       |   date

Este é o arquivo de configuração do cygnus:

E finalmente o arquivo cartodb_keys.conf (sem chave):

         "endpoint": "https://jcarneroatos.carto.com",
         "key": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"   
      }
   ]
}

Atualizar: Após executar o Cygnus no modo DEBUG e verificar os logs, parece que o CARTO está retornando:

{"error":["syntax error at or near \"{\""]}
