Error when calling "receiveMessage" on empty queue (1.5.2, 1.6.2) #1006

Hi!

I'm having a strange behaviour when doing a receiveMessage on an empty queue. The call hangs for approx. 1 minute, and then finishes with:

Error executing "ReceiveMessage" on "http://localhost:9324"; AWS HTTP error: Server error: `POST http://localhost:9324` resulted in a `503 Service Unavailable` response:
      The server was not able to produce a timely response to your request.
      Please try again in a short while!
       Unable to parse error information from response - Error parsing JSON: Syntax error (Aws\Sqs\Exception\SqsException)

Queue URL is configured correctly. The error doesn't happen, if there's a message in the queue. Tested with 1.5.2 and 1.6.2. Any hint is appreciated!

Thanks, Pascal

Hi Pascal, I've added simple test and it passed for both v1 and v2 SDKs (not hanged). https://github.com/softwaremill/elasticmq/commit/c22fd8a797660715e90f6fc108147ca5e7ac6a4e What parameters are you using for CreateQueue and ReceiveMessage commands?
