typo in API reference

[StefPisa]

I need help with FortiSandbox - JSON API Reference. Both 3.2.2 and 4.0.0 versions.
There is a typo in the JSON of request for Upload large file (on-demand submit for filesize > 20MB)
----
"file": filepath 'application/octet-stream'
"data" : {
"url": "/alert/ondemand/submit-file",
----
and I'm unable to understand how it really is. Could you help me? Thanks.
