I have been trying to add uploaded files through the API using PowerShell. The call appears to work correctly when I use it to upload an image file, but if I try the same call with a `synchronous=1` parameter added, it returns with a 500 error.

Based on [a previous topic](https://meta.discourse.org/t/using-the-discourse-api-to-post-with-uploaded-files/29833/20), I had hoped to use the synchronous feature to get the file url.
