Unexpected character - GetReviewsForProduct

[rotemOrbach]

Hi,
I'm using your DLL (yotpo.net version 0.1.0.18)
i'm getting this exception from our logs every once in a while:

Unexpected character encountered while parsing value: <. Path '', line 0, position 0. at Newtonsoft.Json.JsonTextReader.ParseValue() at Newtonsoft.Json.Linq.JObject.Load(JsonReader reader, JsonLoadSettings settings) at Newtonsoft.Json.Linq.JObject.Parse(String json, JsonLoadSettings settings) at YotpoNet.YotpoClient.GetReviewsForProduct(String productID, Int32 pageNum, Int32 resultsPerPage) at GlobalServices.GetYotpoReviewsForProduct(String productid, String productname)

any idea what that might be? it seems that "GetReviewsForProduct" doesn't know how to handle an unexpected value.

thanks
