Request getting http 500 from server when executed by Cypress

[MaxwellCravo]

Hi guys, I have a code that login in the application, fill some fields and then I submit it by clicking in a botton.
Is it a easy thing right? no, it doesn't, I'm trying since this morning submit this shit and I'm still getting this http 500 error.
It happen only when I'm using Cypress. If I do it manually, it works. If I use postman, it works...

Now lets go to the things I guess is the error.

When i'm using cypress I saw my request not sending the origin key in the header. its the only thing different that I found.

I change my chrome web security options to false
I tryed to use the cy.origin() function but it always fail with this message

cy.origin() requires the first argument to be a different domain than top. You passed <myURL> to the origin command, while top is at <myURL>.

I dont know what I can do anymore.

If I don't fix it, I will have to use Robot Framework to automate this project, and guys.... I HATE ROBOT FRAMEWORK.

please help me, how to set my cypress to send the origin on the requests?
