What To Know
This parser error means your input could be interpreted as more than one kind of thing, and Git refuses to guess whether you meant a path or a revision.

Git halted to protect the uncommitted files in your active working directory.
Commands That Trigger This
$git checkout config
Running when you have a file named config and a branch named config
$git log <branch>
Running when the branch name matches a tracked file
Technical Background
01
To solve this, Git uses a double-dash `--` as a standard separator. Everything before `--` is treated as a branch or revision, and everything after is treated as a file path.
02
For example: `git checkout -- build` restores the folder, while `git checkout build --` switches to the branch.
Underlying Causes
A branch name is identical to a file or folder name in the repository
Providing a commit hash that is too short and matches multiple objects
A typo in a command missing the `--` separator
Frequently Asked Questions
The double-dash is a standard POSIX convention used in many command-line tools to signal the end of command options and the beginning of positional arguments.
