Filesize sensor : Configuration error with home-assistant_V2.db file

Hello ,

To monitor the size of the HA DB size , a sensor has been created as per the filesize documentation … File Size - Home Assistant

- platform: filesize
  file_paths:
    - /config/home-assistant_V2.db
    - /config/home-assistant.log

There is a configuration problem when the file extension is “.db” only ,but it is successul if the file extension “.log” for example.

The screenshot of the error

Is it a known issue or just me ?
Thank you to confirm

You “V” is a capitol letter but should be small “v”. Case sensitive.
