Не могу запустить mapping для elasticsearch и yii1.1

При запуске

php yiic elastic map --model=Business --map=data/elasticsearch/florida_es_mapping.json

Выдает ошибку:

    PHP Error[4096]: Object of class stdClass could not be converted to string
    in file *********/YiiElasticSearch/src/YiiElasticSearch/ConsoleCommand.php at line 392

Не пойму даже в какую сторону копать....
