Hello,

Thanks for reaching out, and welcome to the FACEIO support center. To answer your inquiry:

The error you're seeing is related to Cross-Origin Resource Sharing (CORS). CORS is a security feature implemented by web browsers to prevent unauthorized domains from making requests to another domain, which can be potentially harmful. Here's a breakdown of the error message:

• XMLHttpRequest at 'api.faceio.net/deletefacialid' documented here. This indicates that there was an attempt to make an XMLHttpRequest (often used for AJAX requests) to the specified URL from your Vue or React web app.

• has been blocked by CORS policy: This indicates that the browser blocked the request because it violates the CORS policy.

• Response to preflight request doesn't pass access control check: Before making the actual request, browsers send a "preflight" request (using the HTTP OPTIONS method) to check if the actual request is allowed. This error suggests that this preflight request failed its check.

Solution:

• Simply clear your old browser (development) cache, reload your application, and initiate the API call again.
• If the issue persists, you may refer to this StackOverflow thread at: https://stackoverflow.com/questions/54212220/how-to-fix-access-to-xmlhttprequest-has-been-blocked-by-cors-policy-redirect-i on how to deal with the issue on your frontend..
