the website is development mode and is using proxy to tell the development server to proxy any unknown requests to your API server in development. if you have a setup on some server,do enable CORS on your server (https://enable-cors.org/server_expressjs.html).
Here is a sample code for the approach:
<script type="text/x-tmpl" id="tmpl-demo">
app.use(function(request, response, next) {
response.header("Access-Control-Allow-Origin", "*");
response.header("Access-Control-Allow-Methods", "GET, PUT, POST, DELETE");
response.header(
"Access-Control-Allow-Headers",
"Content-type, Accept, x-access-token, X-Key"
);
if (request.method == "OPTIONS") {
response.status(200).end();
}
else {
next();
}
});
</script>
