The Nginx config file parser first parses Nginx string literal
into Lua code
and then Lua code parser parse the Lua string literal "\\s" into the
which is the regex pattern that you want.

Nginx does have builtin support for regex syntax, so does Perl and
context. Unfortunately Lua does not have such built-in regex syntax
support and the ngx.re API was implemented by ngx_lua and by no means

As I said, try using external .lua file and
content/rewrite/access/set_by_lua_file to avoid nginx string escaping
