Possible Solutions
This is a symptom of a larger problem with file handling. The library doesn't currently allow for files to be passed as arbitrary keyword arguments. That's a feature we should probably look into at some point (in a new issue), but for the purposes of this issue we can use an optional argument assignment and the file_or_path util function to achieve the same effect, like in Course.import_outcome. Since assignment isn't mandatory, the implementation will be slightly different.
