Swagger Error with parameters in a multipart post request

I'm trying to document an existing API, built in Node, but it keeps giving me the following error:

"Schema error at paths./upload/Rate.post.parameters[0]
is not exactly one from <#/definitions/parameter>,<#/definitions/jsonReference>"

This error appears in 3 places of my code paths./upload/Rate.post.parameters[0], paths./upload/Rate.post.parameters[1] and paths./users/register.post.parameters[0]

I've searched quite a bit, but, for example, this link did not solved my problem although it's the same error:

Swagger parameter error "is not exactly one from <#/definitions/parameter>"?

Maybe it's something I've missed, maybe I'm just too tired of browsing for an answer over the last few days but I couldn't understand how to solve this. I've added the /users/login path, for example this path works properly, even if it's similar with the /users/register... how come the register gives out an error but the login one does not?

The text got poorly formatted when I copy paste'd it into the website, I believe everything is ok with my indentation(I understand Swagger is sensible about it)

Maybe this will help, but the post route (upload/Rate) should receive a request that will be something like this, once I've parsed it's parameters:

user = req.body.user;
rr = req.files.rate;
overlap = req.body.overlap;
windowT= req.body.window;
latitude= req.body.latitude;
longitude= req.body.longitude;
time= req.body.time;
date= req.body.date;

Thanks for any help anyone can provide.
