NullReferenceException when call SendTransacEmail #54

Closed bahs closed 1 year ago

bahs commented 2 years ago

The code that worked for couple of years started to generate NullReferenceException when we call SendTransacEmail method to send transactional email. Nothing was changed on our side. Upgrading to the last version of library(3.3.0) didn't helped. Our environment is .NET 5, Azure.

Here's the call stack System.NullReferenceException: at RestSharp.Portable.ParameterKeyComparer.Compare (FubarCoder.RestSharp.Portable.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=be81bb0f53eab22f) at RestSharp.Portable.ParameterKeyComparer.Equals (FubarCoder.RestSharp.Portable.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=be81bb0f53eab22f) at System.Collections.Generic.Dictionary2.FindValue (System.Private.CoreLib, Version=5.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e) at System.Collections.Generic.Dictionary2.TryGetValue (System.Private.CoreLib, Version=5.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e) at RestSharp.Portable.MultiValueDictionary`2.TryGetValue (FubarCoder.RestSharp.Portable.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=be81bb0f53eab22f) at RestSharp.Portable.ParameterCollection.AddOrUpdate (FubarCoder.RestSharp.Portable.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=be81bb0f53eab22f) at RestSharp.Portable.RestClientBase.set_UserAgent (FubarCoder.RestSharp.Portable.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=be81bb0f53eab22f) at sib_api_v3_sdk.Client.ApiClient.CallApi (sib_api_v3_sdk, Version=3.3.0.0, Culture=neutral, PublicKeyToken=null) at sib_api_v3_sdk.Api.TransactionalEmailsApi.SendTransacEmailWithHttpInfo (sib_api_v3_sdk, Version=3.3.0.0, Culture=neutral, PublicKeyToken=null) at RT.Utils.SendInBlueService.SendEmailMessage (RT, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null: D:\home\site\repository\RT\Utils\SendInBlueService.cs:848)

If we restart the server - everything works good for about 1 day, after that we get this exception again.
