Error "no notification handler registered" on diff

[jens1205]

Describe the bug
Using vim-fugitive, the command ":Git difftool -y master" spams me several (4) times with the error message.

Comment #44 (comment) looks similar

no notification handler registered for "/Users/myuser/.local/share/nvim/site/pack/packer/start/vim-ultest/rplugin/python3/ultest:function:_ultest_update_positions"

Enabling debug logs shows nothing, no matter if the command is started manually or via commandline (ULTEST_LOG_LEVEL=DEBUG ULTEST_LOG_FILE=vim-ultest.log nvim -c ":Git difftool -y master")

To Reproduce
:Git difftool -y

Expected behavior
No error

Screenshots
n/a

Additional context
