Hi all,
I'm trying to develop an application to work with the trello API (https://github.com/karipov/tagtrack). I use python's aiohttp module.
However, even though I provide all the necessary mimeType and extension information, the attachements on my cards added through the API, when downloaded, have no extension, nor mimeType information:

What am I doing wrong? or is this an issue from Trello?
