It is not "double slash". It is "the argument to try files (before
variable expansion) ends in slash".

https://nginx.org/r/try_files

"""
The path to a file is constructed from the file parameter according to
the root and alias directives. It is possible to check directory’s
existence by specifying a slash at the end of a name, e.g. “$uri/”.
"""

$foo does not end in slash, so try_files looks for a file of that
(expanded) name, and fails to find it.

$foo/ does end in slash, so try_files looks for a directory of that
(expanded) name, and finds it and serves it (which involves a
subrequest/internal redirect).
