Exception after sending mail about csharp-sparkpost HOT 11 CLOSED

I haven't figured it out yet. If I had to guess right now, there's something in your request that's causing a null error on the way out. Still investigating...

from csharp-sparkpost.

Can you try this advice here: https://github.com/SparkPost/csharp-sparkpost#special-note-about-async

Just to double-check that it's not this issue?

Closing just because I haven't heard back. My time is worth... something. 👅 ⌚ ⏳

Hi Darren,
of course... We figured out this was due to the reasons explained in the
link I sent you on slack. Thanks for the help

We're receiving a very similar error as to what was described above. The email sends successfully but immediately after a System.NullReferenceException is raised and the w3wp.exe process is terminated.

The code we're using is very similar to the sample code in the documentation and are working with version 1.2.0.

Would it be possible to get a copy of the entire project or solution?

I ask not because I've asked for code samples from people, but... the code samples always "work for me."

There's something deeper, but I'm guessing as to what it can be.

Another option is... this library is relatively small. Could you bring it into your solution raw, run it through a debugger, and tell me exactly where it is throwing?

@waglons Here is the code sample of the person that figured it out:

 Task.Run(async () =>
                    {
                        await client.Transmissions.Send(transmission);
                        transmission.Options.StartTime = new DateTimeOffset(deliveryTime).ToOffset(TimeSpan.FromHours(1));
                        transmission.Content.Subject = new DateTimeOffset(deliveryTime).ToOffset(TimeSpan.FromHours(1)).ToString();
                        await client.Transmissions.Send(transmission);
                        transmission.Options.StartTime = new DateTimeOffset(deliveryTime).ToOffset(TimeSpan.FromHours(2));
                        transmission.Content.Subject = new DateTimeOffset(deliveryTime).ToOffset(TimeSpan.FromHours(2)).ToString();
                        await client.Transmissions.Send(transmission);
                        transmission.Options.StartTime = new DateTimeOffset(deliveryTime).ToOffset(TimeSpan.FromHours(3));
                        transmission.Content.Subject = new DateTimeOffset(deliveryTime).ToOffset(TimeSpan.FromHours(3)).ToString();
                        await client.Transmissions.Send(transmission);
                    }
                  ).Wait();

^^^ I can't vouch for that code, but it might provide some clue.

from csharp-sparkpost.

The code was helpful. While putting together a solution for you to review I noticed an issue with my asynchronous call and was able to correct it.

Thanks for your help.

from csharp-sparkpost.

Glad it helped!

It might help me... I think I might put in a sync mode, hidden behind the Task<T> contract.

@waglons @altozar Version 1.3.0 has just been released with sync support.
