Make sure you have the latest version of abapGit installed, see upgrading, after updating try again.
If the error persists, submit an issue to the maintainer of the repository requesting to update to latest version of abapGit serialized files pointing to the guide below.
Or alternatively install an old version of abapGit to allow for installing the files, see next section "For maintainers"
If the latest version of abapGit is installed and the erorr message is shown, then the serialized files should be updated to the latest version.
The steps are:
Install the old abapGit version, matching the serialized files
Install the objects into the ABAP system
Install the newest abapGit version
Use the new abapGit to save the files to the git repository
This will overwrite the files in the repository to have the latest format, compatible with the newest abapGit release.
