I have a working access_token with every available permission in the Graph explorer page granted.

I am able to aparently upload a video chunk by chunk without problems. Once I finish uploading it I do indeed get a file handle along the lines of {'h': '4::: ....'}. However I am getting an error when trying to actually publish it. The publish request returns the aforementioned error #100, but I don't know what other permission should I need. My acoount is a business account, does it need to be business verified?

The docs are not very clear either as in the video-api/guides/publishing page, guide says to use the graph-video.facebook.com url but it seems deprecated? Anything I am missing? Thanks.
