Every time I upload disk via API it failed on following exception:

 2016-12-07 09:06:58,529 ERROR   (Thread-1) [web] Failed to dispatch request
Traceback (most recent call last):

    raise HTTPForbidden("Content-Length(%d) out of allowed range(%d)" %( size, ticket['size']))
HTTPForbidden: Content-Length(8388608) out of allowed range(1024)

The failed code is here:

When I remove this condition everything works fine.

The code I use to upload disk is here:
