CORS Error
JavaScript
Network Errors
Error Message
Access to fetch has been blocked by CORS policy
What Causes This Error?
Cross-Origin Resource Sharing (CORS) blocks requests from different origins for security. The server must explicitly allow cross-origin requests.
Solution
Configure CORS headers on your server, or use a proxy during development. Never disable CORS for production.
