KeyError('Path') exception is being thrown

[blt-r]

If I try to use any command (except for --help), an exception is thrown.

$ mons list
KeyError('Path')
An unhandled exception has occurred.
Use the --debug flag to disable clean exception handling.

$ mons add steam ~/.local/share/Steam/steamapps/common/Celeste
KeyError('Path')
An unhandled exception has occurred.
Use the --debug flag to disable clean exception handling.

I am on Arch Linux and this happens whether I install mons from AUR, pip, or build from saurce.

Full stack trace:

$ mons --debug help
An unhandled exception has occurred.

[blt-r]

The problem was that I had this in my installs.ini:

[DEFAULT]
preferredbranch = stable

[steam-flatpak]

I had previously used steam flatpak, but now I am using native package. I guess at some point it saw that the path I specified for the installation didn't exist and tried to remove the installation, but didn't remove the entry for it, instead only removing the path field. And then tried to access that field, which caused the exception.

Fixing the corrupt config file solved the issue
