Response for preflight has invalid HTTP status code 404 in AngularJS - angularjs

Question

I am trying to use Angular's POST and PUT methods but I keep getting the error:
Response for preflight has invalid HTTP status code 404
My code:
$http({
method: "POST",
url: "http://localhost:4567/api/v1/project",
data: project_data
}).then(function successCallback(response) {
console.log(response);
}),
function errorCallback(response) {
console.log('error!');
console.log(response);
}
$http({
method: "PUT",
url: "http://localhost:4567/api/v1/project/1",
data: data
}).then(function successCallback(response) {
console.log(response);
}),
function errorCallback(response) {
console.log('error!');
console.log(response);
}
Does anyone know what might be going on or how to fix it? Other solutions I've found involve changes to the server side code (in this instance, I don't have access to the server). Thanks in advance!

If you use Node.js, just do this:
app.options('/api/v1/project/1', function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Content-Type, Content-Length, Authorization, Accept,X-Requested-With");
res.header("Access-Control-Allow-Methods","PUT,POST,GET,DELETE,OPTIONS");
res.header("Content-Type", "application/json;charset=utf-8");
res.status(204);//important
res.end()
});
app.put('/api/v1/project/1', function(req, res, next) {
...your normal code here
})
