Notification shown when `sftp.upload.activeFile` action is triggered from keyboard shortcut

Every time when I trigger sftp.upload.activeFile action using keyboard shortcut (Ctrl+Shift+U) the file in not uploaded and a notification pops up:

Cannot read properties of null (reading '$mid')

However, the notification doesn't appear when triggering the action using editor context menu or command palette. I don't have any other keyboard bindings that could conflict with this one and the keyboard shortcut troubleshooter doesn't show any issues. Even changing the shortcut doesn't change the behavior.

To Reproduce Steps to reproduce the behavior:

1. Configure a keyboard shortcut for sftp.upload.activeFile action
2. Open a file
3. Keep focus in editor
4. Hit the configured keyboard shortcut
5. Message pops up

Expected behavior No notifications
