AssertionError when the file is unsuccessfully attached to the message

[dmfigol]

This error is intermittent and it seems it pops up when the file was not successfully attached to the message by the webex teams backend. I can't reproduce it consistently, but I encountered this problem already twice.

  File ".../.venv/lib/python3.6/site-packages/webexteamssdk/api/messages.py", line 210, in create
    data=multipart_data)
  File ".../.venv/lib/python3.6/site-packages/webexteamssdk/restsession.py", line 393, in post

    if request.body else "")
  File ".../.venv/lib/python3.6/site-packages/webexteamssdk/exceptions.py", line 45, in _to_unicode
    assert isinstance(string, basestring)
AssertionError

I was sending a message using
api.messages.create(roomId="id", markdown="text", files=["path/to/file1"])

Hi @dmfigol, I have been able to reproduce the issue. This happens when the request contains a mime-encoded file and the request fails. As you know from #62 the errors contain a verbose error message that includes the full HTTP request and response. This AssertionError is happening when attempting to convert the mime-encoded file to a string.

I'll kill two birds with one stone by simplifying the default error messages and include the request and response exchange as an optional method on the error.

@dmfigol this issue was resolved with the simplified error messages - released in v1.1. Thank you for catching and reporting this issue!
