Directline attachments don't work anymore

Describe the bug Trying to upload an attachment using the latest version of the directline connector does not work anymore. The emulator will send an error back that path is not available in unknown. Downgrading to one older version will make it work again.

To Reproduce Use MEDIA with a directline convo and connect to a local bot through the botframework emulator.

Expected behavior Upload works and id for attachment is being returned.

Oh, that is quite an interesting – quite an annoying issue with fetch. I tried he branch and it worked as expected. Thanks 👍🏼

Now this is a nice one. What I found out:

• It seems as if node-fetch 2.5.1 cannot handle the Content-Type header correctly, as compared to 2.3.3 (dependency was updated with 0.0.15). Didn’t dive into detail, but removing this header when uploading the attachment helped.
• And with node-fetch 2.5.1 somehow the response handling changed, I had to rewrite two code lines - you are working with local file attachments, so this was not the problem in your case.
• The Bot Framework Emulator requires an activity for the file upload - the Azure bot service does not. But both of them are fine with an empty activity, if no text is given in Botium.

The pull request is there, and it will be merged with the October release. Maybe you can check out the branch and test it: https://github.com/codeforequity-at/botium-connector-directline3/pull/31
