[Solved] Exception in Unity IAP on Google Play

Unity 5.4.2
Unity IAP 1.8.3

I'm connected to the uk google play store, I have an app in beta, and everything is generally working fine.

I'm at the stage where I'm translating the app in multiple languages, and testing that.

When I change the handset (samsung galaxy S5 and S6 Edge both exhibit this) to french, and launch the app, I get the following error in the log, and the store never becomes available.

10-21 04:12:16.122: I/Unity(4164): FormatException: Invalid character at position 1

Changing the handset to Italian, German, Spanish and Italian, and then launching the app works fine though.

Any Ideas?

 

Haven't been able to get the workaround to work as of yet

 

I have fixed this issue by replace the function UnityEngine.Purchasing.JSONSerializer.DeserializeMetadata in Stores.dll with the following function. I had to replace TryGetString with an inline implementation as ILSpy + Reflexil don't allow you call extension methods.

Code (CSharp):

1.     static UnityEngine.Purchasing.ProductMetadata DeserializeMetadata(System.Collections.Generic.Dictionary<string, object> data)
2.     {
3.         string localizedPriceString = null;
4.         if (data.ContainsKey("localizedPriceString")) { localizedPriceString = data["localizedPriceString"].ToString();}
5.  
6.         string localizedTitle = null;
7.         if (data.ContainsKey("localizedTitle")) { localizedTitle = data["localizedTitle"].ToString();}
8.  
9.         string localizedDescription = null;
10.         if (data.ContainsKey("localizedDescription")) { localizedDescription = data["localizedDescription"].ToString();}
11.  
12.         string isoCurrencyCode = null;
13.         if (data.ContainsKey("isoCurrencyCode")) { isoCurrencyCode = data["isoCurrencyCode"].ToString();}
14.  
15.         string localizedPriceAsString = data["localizedPrice"].ToString();
16.         Debug.Log("LocalisedPrice: " + localizedPriceAsString);
17.  
18.         decimal localizedPriceAsDecimal;
19.         if (!decimal.TryParse(localizedPriceAsString, out localizedPriceAsDecimal))
20.         {
21.             localizedPriceAsDecimal = decimal.Parse(localizedPriceAsString, System.Globalization.NumberStyles.Any, System.Globalization.CultureInfo.CreateSpecificCulture("en-GB"));
22.         }
23.  
24.         return new ProductMetadata(localizedPriceString, localizedTitle, localizedDescription, isoCurrencyCode, localizedPriceAsDecimal);
25.     }
