Unexpected exception when setting up integration

[surfingbytes]

First, add custom repository to HACS and add this integration. Then, add Paperless HA integration and you'll get configuration window asking for host, port, username, etc.. This window has 2 bugs:

• Port is ignored. No matter what you specify, it uses 8000. This means you can't use reverse proxy (paperless.homelab.local on 80 for example), but you have to expose the 8000 port and use ip address in this settings.
• TODO Tag (optional) is not optional. When you don't specify it, the configuration fails:
  Traceback (most recent call last): File "/config/custom_components/paperless_ng/config_flow.py", line 118, in async_step_user info = await validate_input(self.hass, user_input) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/config/custom_components/paperless_ng/config_flow.py", line 97, in validate_input "todo_tag": data["todo_tag"], ~~~~^^^^^^^^^^^^ KeyError: 'todo_tag'
