Reports

You can’t use async/await or Promises in beforeunload handlers.

Option 1: Use sendBeacon + server-side token recognition
If possible, send a token or userId as part of the payload (not header), e.g.:

navigator.sendBeacon('/api/unlock', JSON.stringify({ userId, token }));

Option 2: Use fetch with keepalive: true (limited support):

fetch('/api/unlock', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer yourTokenHere'
  },
  body: JSON.stringify({ userId }),
  keepalive: true
});enter image description here
