GM_cookie.set and GM_cookie.delete API are not functioning

[cloudswave]

The GM_cookie.list API is OK, but when I try to invoke GM_cookie.set and GM_cookie.delete APIs, they are not functioning. Can you help me?
The tampermonkey document
Example:

GM_cookie.set({
  url: 'https://example.com',
  name: 'name',
  value: 'value',
  domain: '.example.com',
  path: '/',
  secure: true,
  httpOnly: true,
  expirationDate: Math.floor(Date.now() / 1000) + (60 * 60 * 24 * 30) // Expires in 30 days
}, function(error) {
  if (error) {
    console.error(error);
  } else {
    console.log('Cookie set successfully.');
  }
});

GM_cookie.delete({ name: 'cookie_name' }, function(error) {
    if (error) {
        console.error(error);
    } else {
        console.log('Cookie deleted successfully');
    }
});

The problem was mainly that your script missed the domain parameter, which is now required by Chromium browsers.
Now this is fixed, as I add the default domain paremeter.

Verified, the problem has been fixed. Thanks
