Newtonsoft.Json versioning issue while attempting to authenticate with JWT using DocuSign.eSign

[ha-cmhheli]

Not sure what I'm doing wrong if anything but I can't get basic JWT authentication working with the latest package Scenario: .NET 4.7.2 c# Test project Using DocuSign.eSign.dll v5.9.0 No other nuget packages added Very simple test method.
This line: ApiClient apiClient = new ApiClient(@"https://www.docusign.net/restapi"); appears to need Newtonsoft.Json v11.0.2 This line: OAuthToken authToken = apiClient.RequestJWTUserToken(clientId, userId, oathPath, Encoding.UTF8.GetBytes(rsaKey), expiresIn1Hour, scopes); appears to need Newtonsoft.Json v10.0.0.0

[TestMethod]

    public void TestAuth()
    {
        string clientId = ""; // removed for issue
        string userId = ""; // removed for issue
        string oathPath = @"https://account.docusign.com/oauth/auth";

        ApiClient apiClient = new ApiClient(@"https://www.docusign.net/restapi");

        int expiresIn1Hour = 1;
        string rsaPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "RSAPrivateKey.txt");
        string rsaKey = System.IO.File.ReadAllText(rsaPath);
        var scopes = new List<string> { "signature" };

        OAuthToken authToken = apiClient.RequestJWTUserToken(clientId, userId, oathPath, Encoding.UTF8.GetBytes(rsaKey), expiresIn1Hour, scopes);

        Assert.IsNotNull(authToken);
    }

Error: System.TypeInitializationException HResult=0x80131534 Message=The type initializer for 'System.IdentityModel.Tokens.Jwt.JsonExtensions' threw an exception.

I am having the same issue, except I'm on .NET 5, and with the same DocuSign.eSign.dll version as you (5.9.0), mine is complaining that it can't find Newtonsoft.Json, Version=11.0.0.0. I did go ahead and install the Newtonsoft.Json nuget package, which did not work. I also tried adding a binding redirect for it in web.config and that also did not work.

I wanted to reach out to see if you're still experiencing this issue. I haven't been able to reproduce it in a .NET 4.7.2 test project using the 5.9.0 version of the eSign NuGet package. Using the code snipped that you provided, my test method compiles and completes successfully in Visual Studio 2022. The only NuGet package added to my test project was the eSign NuGet package and my test project has only the one test method.

Which version of Visual Studio are you using? Also, are there any other dependencies in your test project?

Hi, This issue has been resolved with binding redirects in the config file. Thanks, Heather
