Error while trying to install sparkfun boards

[mobacon]

Describe your environment
I use the Sloeber plugin (Version 4.4.1) in Eclipse 2022-09
OS: Windows 10 and Kubuntu 22.04

Describe the bug
After adding a new board source I get an error when I want to install boards.

To Reproduce
Steps to reproduce the behavior:

1. Go to Preferences | Sloeber | Third party index url's
2. Add the URL https://raw.githubusercontent.com/sparkfun/Arduino_Boards/main/IDE_Board_Manager/package_sparkfun_index.json
3. Go to Preferences | Sloeber | Platforms and Boards
4. Click on the first Sparkfun checkbox
5. See the error report: An error has occurred. See error log for more details.
   Cannot read the array length because "inScopeVersions" is null

Expected behavior
I can select one of the Sparkfun AVR boards from the list.

Sorry for wasting your time!

Not sure it is the same problem as your report does not state this is a sloeber install in the latest eclipse version.

Updated my report with eclipse version. I think it is the latest at this time: 2022-09
