GooglePlacesSDK Error 500

I am getting error from google places:

{
    "error": {
        "errors": [{
            "domain": "global",
            "reason": "backendError",
            "message": "Backend Error"
        }],
        "code": 500,
        "message": "Backend Error"
    }
}

      

        
        
        
      

    

I am using version Google Places API for iOS

2.0.0

. The error looks strange. Is there anyone who experienced this and helped me get rid of this error?
