THIS IS THE ERROR:The error message you're seeing is related to the Permissions-Policy HTTP header. This header allows a site to control which features and APIs can be used in the browser.

The ch-ua-form-factor is not a recognized feature for the Permissions-Policy header. It's actually part of the User-Agent Client Hints API, which allows developers to access information about the user's device in a privacy-preserving way.

If you're seeing this error, it's likely that there's a misconfiguration in your server's HTTP headers. You might have added ch-ua-form-factor to the Permissions-Policy header, but it doesn't belong there.

To fix this issue, you should remove ch-ua-form-factor from the Permissions-Policy header. If you need to access information about the user's device form factor, you should use the User-Agent Client Hints API directly, not through the Permissions-Policy header.

If you're not directly managing your server's configuration, this error might be caused by a third-party service or library that you're using. In that case, you might need to contact the service provider or update the library to a version that doesn't include this misconfiguration.The Permissions-Policy header is typically set by the server hosting the web application, not by the domain name provider or the DNS service. In your case, this would likely be Railway.

However, Cloudflare does have some influence over HTTP headers as it acts as a reverse proxy. It can add, remove, or modify certain HTTP headers. But it's unlikely that Cloudflare would add a Permissions-Policy header with an unrecognized feature.

To confirm where the header is coming from, you could temporarily bypass Cloudflare by changing your DNS settings to point directly to your Railway server, then check the HTTP headers to see if the Permissions-Policy header is still present. If it is, then the header is likely being set by Railway. If it's not, then it may be added by Cloudflare.

Remember to change your DNS settings back after you're done testing, as bypassing Cloudflare would also bypass its security and performance features.--------------Please help :)
