Can't set host headers in Cypress - header

Question

I'm having an annoying issue.
I want to send a request with Cypress, and it is like follows:
cy.request({
method: 'POST',
url: 'http://myUrl.com/a/nice/path',
body: {email: email},
});
And it fails:
The request we sent was:
Method: POST
URL: http://backend-openpay-pe.test.geopagos.com/api/registrations/send-code
Headers: {
"Connection": "keep-alive",
"user-agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/106.0.5249.119 Safari/537.36",
"accept": "*/*",
"accept-encoding": "gzip, deflate",
"referer": "aNiceReferer"
}
Redirects: [
"308: http://myUrl.com/a/nice/path"
]
And the status code from the response is 404.
When I try to set the host header as follows:
cy.request({
method: 'POST',
headers: {
host: 'myUrl.com',
},
url: 'http://myUrl.com/a/nice/path',
})
The log from Cypress was:
The request we sent was:
Method: POST
URL: http://backend-openpay-pe.test.geopagos.com/api/registrations/send-code
Headers: {
"Connection": "keep-alive",
"user-agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/106.0.5249.119 Safari/537.36",
"accept": "*/*",
"accept-encoding": "gzip, deflate",
"referer": "http://myUrl.com/a/nice/path"
}
Redirects: [
"308: http://myUrl.com/a/nice/path"
]
And again, a response with 404. What I can see in the previous response, is that Cypress is not sending the host header, even when I manually set it. I tried testing some other headers:
cy.request({
method: 'POST',
headers: {
host: 'myUrl.com',
banana: 'MonkeyLikesBananas',
},
url: 'http://myUrl.com/a/nice/path',
})
And the log was:
The request we sent was:
Method: POST
URL: http://backend-openpay-pe.test.geopagos.com/api/registrations/send-code
Headers: {
"Connection": "keep-alive",
"banana": "MonkeyLikesBananas",
"user-agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/106.0.5249.119 Safari/537.36",
"accept": "*/*",
"accept-encoding": "gzip, deflate",
"referer": "http://myUrl.com/a/nice/path"
}
Redirects: [
"308: http://myUrl.com/a/nice/path"
]
Again, Cypress seems to correctly send any header I set, except for host, that for some reason is missing there.
Cypress version:
$ npx cypress -v
Cypress package version: 10.9.0
Cypress binary version: 10.9.0
Electron version: 19.0.8
Bundled Node version: 16.14.2
Any help will be welcome.
Thanks!
