EnvelopesApi sync methods dead lock net48 WebForms. Issue since 6.1 version.

EnvelopesApi sync methods dead lock net48 WebForms. Issue since 6.1 version.

It looks like GetAwaiter doesn't work well in WebForms.

I confirm that latest console code example works perfectly. However when in WebForms, then EnvelopesApi sync methods are dead on arrival.

I didn't test WebForms Async tricks with EnvelopesApi async methods.

Hello there,

Before we dive in, I need some clarification. Please answer the questions below:

1. Does this work in previous versions (e.g.: 6.0)?
2. What is the error message you're getting? Do you have a log?
3. What exactly do you mean by "However when in WebForms, then EnvelopesApi sync methods are dead on arrival"?

Thanks, Leandro

Please find below answers:

1. Yes it works fine in previous version 6.0
2. There is no error message. Or I didn't wait long enough to see the error.. The underlying call to DocuSign API works. Envelope is created. However the method call to EnvelopesApi.CreateEnvelope just never returns.
3. I mean version 6.2 works fine in net48 Console application. However it doesn't work in net48 ASP.NET Web Forms application. Method call to EnvelopesApi.CreateEnvelope never returns.

I guess the following GetAwaiter() doesn't work in ASP.NET Web Forms.

return CreateEnvelopeAsyncWithHttpInfo(accountId, envelopeDefinition, options) .ConfigureAwait(false) .GetAwaiter() .GetResult();

Special considerations should be taken to use Asynchronous methods in ASP.NET Web Forms. https://learn.microsoft.com/en-us/aspnet/web-forms/overview/performance-and-caching/using-asynchronous-methods-in-aspnet-45

Hello there, could you provide a small code sample that replicates your issue?

Set your ClientId and ImpersonatedUserID in web.config Put private key file and lorem.pdf in C:\Temp_files

Perhaps the same issue: calling TemplatesApi.Get returns an EnvelopeTemplate in DocuSign.eSign 6.0, but hangs forever in 6.1+ and freezes the UI.

This works fine in a console application, but not in Windows Forms.

Sample code:

            try
            {
                var apiClient = GetRestApiClient();
                var templatesApi = new TemplatesApi(apiClient);
                template = templatesApi.Get(accountId, templateId);                
            }
            catch (ApiException ex)
            {
            }
            catch (Exception ex)
            {
                return ex.Message;
            }

No errors are not caught. Fiddler shows a successful 200 and response with the template JSON.

Just wanted to provide a quick update on this issue - the team was able to re-produce the issue and is currently looking into a fix.

We just ran into the same issue with .NET 4.8 synchronous methods and any version of the client over 6.0.

@kenharris any eta on a fix?

[kenharris]

@Welchen I'm not aware of a specific ETA just yet. I'll see what I can find out and report back when I have something more specific.

[kenharris]

A new update was just released moments ago - v6.4.1 - which should have a fix to address this issue.

I'm going to close this for now. Feel free to re-open if the issue persists, or just open a new issue.
