static: is a file not a directory

[Ben]

in the case that the path is a file, not a dir, this error can be confusing https://github.com/encode/starlette/blob/master/starlette/staticfiles.py#L59C8-L59C81

if the path is a file it will say "Directory '{directory}' does not exist", which doesn't make sense. the path does exist its a file, not directory, so an error message like "Path is a file not a directory" would be clearer.
