To make the health check process faster, I wrote path for it: app.get('/healthz', (req, res) => What you return on your health check path is up to you, but we recommend running quick sanity checks (like a simple database query) and returning an “OK” 200 response or an empty 204 response if the app is healthy. Set preflightĪllowMethods.includes(req.headers) &ĪllowHeaders.includes(req.headers)

#'access control allow origin' code#

The following code works fine on Firefox, but Chrome seems to send preflight request twice with one fail and one succeed which turns out to be a bug on chrome itself. I tried to connect my static site on render to my local server for debugging my request on my browser developer tool. Res.setHeader('Access-Control-Max-Age', 7200) Chromium (starting in v76) caps at 2 hours (7200 seconds). Firefox caps this at 24 hours (86400 seconds). Res.setHeader('Access-Control-Allow-Private-Network', true) Res.setHeader('Access-Control-Allow-Credentials', true) 'Content-Type, Authorization, X-Content-Type-Options, Accept, X-Requested-With, Origin, Access-Control-Request-Method, Access-Control-Request-Headers' 'GET,HEAD,PUT,PATCH,POST,DELETE,OPTIONS,CONNECT,TRACE' My solution for “No ‘Access-Control-Allow-Origin’ header” : const express = require('express')

Timed out after waiting for internal health check to return a successful response code.

No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

If there are some context incorrect, feel free to point out. To be clarified, this is my solutions based on my assumptions that may not works perfectly in other case. My deployment works fine now, so I would like to share how I managed to solve these issues. Jun 15 02:18:13 PM Server runs on port 10000Īny suggestions would be highly appreciated.

Enter Access-Control-Allow-Origin as the header name.

In the Custom HTTP headers section, click Add.

Right click the site you want to enable CORS for and go to Properties.

Otherwise please follow the guidelines for different architectures below in order to set this header and permit outside domain. If this page is intended to be accessible to everyone, you don't need to take any action. The only case where this is appropriate when using the same-origin policy is when a page or API response is considered completely public content and it is intended to be accessible to everyone. This is generally not appropriate when using the same-origin security policy.

Unless this HTTP header is present, such 'cross-domain' requests are forbidden by web browsers, per the same-origin security policy.

Cross-origin resource sharing (CORS) is a mechanism that allows resources (e.g., fonts, JavaScript, etc.) on a web page to be requested outside the domain from which the resource originated.
