Ah, sorry the typo is on me from copying the wrong command from the 
shell history. It produces the same output with using LICENSES as path.

$ git last-modified -- LICENSES
fatal: ambiguous argument 'LICENSES': unknown revision or path not in 
the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
