Video Addon Fitness Blender stopped working

The Video Addon “Fitness Blender” gives an error on a PI 3b+. The last weeks i often used it, today i noticed, it stopped working. I tried [2020.03-1] & [2020.06-1] images, but the error remains the same.
Here is the log:

Thanks for your support.

You will need to query this with the developer of the addon but it looks like it no longer being maintained.

                                              File "/home/osmc/.kodi/addons/", line 63, in get_videos
                                                returnedVideos = resp["items"]
                                            KeyError: 'items'

There have not been any updated for almost 3 years.

Thank you. I will try to contact him.
