ACK Console Error Reference

The Alexa Connect Kit developer console validates the capabilities that you enter. If there is an error, the error code, the path to the attribute that has the error, and information about the error appear in the console.

CONTAINS_INVALID_CHAR

The CONTAINS_INVALID_CHAR error occurs if a value contains a character that isn’t valid. The following shows an example where value.text has the value "hello!!!!", where the character ! isn’t valid.

{
  "type": "AlexaInterface",
  "version": "3",
  "instance": 99,
  "capabilityResources": {
    "friendlyNames": [

          "text": "hello!!!!",
          "locale": "en-US"
        }
      }
    ]
  }
}

DUPLICATED_BASIC_CAPABILITIES

The DUPLICATED_BASIC_CAPABILITIES error occurs if you specify the same basic capability more than once. The following shows an example that specifies the same capability twice.

[
  {
    "type": "AlexaInterface",
    "version": "3",
    "properties": {
      "supported": [

        }
      ]
    }
  }
]

DUPLICATED_PRIMITIVE_CAPABILITY_INSTANCES

    "proactivelyReported": true,
    "retrievable": true,
    "readOnly": true
  },
  "interface": "Alexa.PowerController"

   ],
    "proactivelyReported": true,
    "retrievable": true,
    "readOnly": true
  },
  "interface": "Alexa.PowerController"
}

            }
          ]
        }
      }
    ]
  }

        }
      }
    ]
  }
}

INVALID_INTERFACE

The INVALID_INTERFACE error occurs if you refer to an interface that ACK doesn’t support. For details, see Supported Alexa smart home capabilities and List of Capability Interfaces and Supported Locales. The following shows an example that isn’t valid because Alexa doesn’t support the RandomController interface.

        }
      }
    ]
  }
}

OUT_OF_RANGE_VALUE

The OUT_OF_RANGE_VALUE error occurs if an attribute has a value that is out of range. The following shows an example where instance is 1000000000000, which is too large. The value for instance must be no more than 2^31.

          ]
        }
      }
    ]
  }
}

RANGE_NOT_SUPPORTED

The RANGE_NOT_SUPPORTED error occurs if you specify a range and specify a value that isn’t in the range. The following shows an example where the rangeValue of 3.141 isn’t in the specified range.

        }
      }
    ]
  }
}

    ]
  }
}

WRONG_VALUE

The WRONG_VALUE error occurs if an attribute contains a different value than expected. The following shows an example where type has the unexpected value NotAnAlexaInterface.

{
  "type": "NotAnAlexaInterface",
