For anyone that might look at this, the docs are not super helpful when trying to upload a story. If you are in the US,

https://api-us.storyblok.com/v1/spaces/

Is the fetch url.

NOT mapi, or v2, this is the exact one that finally worked.

It ONLY seems to say that here: https://www.storyblok.com/docs/api/management/getting-started/

I spent hours on this hopefully this helps someone some day.
