title: amazon s3 upload from react : forbidden
body: <p>I use S3FileUpload from react-s3 to upload</p>
  <pre><code>const config = {
    bucketName: &quot;bucketName&quot;,
    dirName: &quot;dirName&quot;,
    region: &quot;eu-west-3&quot;,
    accessKeyId: KeyId,
    secretAccesKey: secretKey,
  };
  </code></pre>
  <p>I use keyId and secretKey to upload file from my react application. But I have an error 403 Forbidden.</p>
  <p>My CORS configuration is OK and my bucket is public.</p>
