In theory, this *should* work (though the extra space before the
"<cr>" can be optionally removed, as can the two trailing "/"
characters). And, if tried in a raw session of Vim (using "-u
custom_vimrc" at startup, where "custom_vimrc" contains just

set nocp
nmap <leader>w :%s/\s\+$// <cr>
" nnoremap <leader>w :%s/\s\+$<cr>

This suggests that...

you have some other mapping that is interfering, perhaps created by a
plugin. I'd check the output of ":map" to see if something else has
been mapped to that sequence.

I'd also default to using "nnoremap" unless I had reason to use
"nmap" otherwise. I don't think that has anything to do with this
case, but by defaulting to nnoremap, I find I'm less likely to
surprise myself in the few cases where it really would make a
difference.
