Following directions, I receive the error - 'invalid_arguments'

Hi,

I was following your directions step 1 - 8 to add access, then used the code 'Posting your first message'.

After the call to PostMessageAsync, I received invalid_arguments in the json.

Thanks

I rechecked the example from https://github.com/Inumedia/SlackAPI/wiki/Examples and it's working properly. Could you post your code?
