FOSElasticaBundle: "Error: Wrong parameters for Exception(..)" - while populating FOSElasticaBundle/Symfony2

Hi,

I’m having the same issue as described here in this stackoverflow question (after upgrading elasticsearch from 1.7.3 => 2.0):

Error: Wrong parameters for Exception([string $exception [, long $code [, Exception $previous = NULL]]])

http://stackoverflow.com/questions/33229423/error-in-responseexeption-while-populating-foselasticabundle-symfony2

I was using elasticsearch 1.7.3 with foselasticabundle, but after upgrading elasticsearch to 2.0, and running console fos:elastica:populate --no-debug, I get the following error & trace:

~/Sites/webapp $ console fos:elastica:populate --no-debug

Resetting app

Any ideas on a fix?
