React native fetch/XMLHttpRequest post request with multiple set-cookie - react-native

Question

I want to receive multiple Set-Cookie values from a web server.
Currently i'm only receiving the last Set-Cookie in my header.
XMLHttpRequest:
var formData = new FormData();
formData.append('userId', state.userId);
formData.append('password', state.password);
var http = new XMLHttpRequest();
var url = "http://myurl";
http.open("POST", url);
http.setRequestHeader("Content-type", "multipart/form-data");
http.withCredentials = true;
http.onreadystatechange = function() {//Call a function when the state changes.
if(http.readyState == 4 && http.status == 200) {
console.log(http.responseText);
console.log(http.getAllResponseHeaders());
}
}
http.send(formData);
Fetch:
fetch('http://myurl', {
method: 'POST',
headers: {
'Content-Type': 'multipart/form-data',
},
credentials: 'same-origin',
body: formData
})
.then((response) => {
console.log(response);
console.log(response.headers.getAll('set-cookie'));
return response.json()
})
.then((responseJson) => {
console.log('responseJson', responseJson);
console.log('formData', formData);
setLoginBool(responseJson.success);
})
.catch((error) => {
console.error(error);
});
I have added the result of a postman request and the log of the fetch result.
It seems only the last Set-Cookie value is being received.
