It seems this kind of joke in red bold caused issue.
in
https://github.com/niva-xx/vim9-diff-enhanced/blob/master/autoload/EnhancedDiff.vim
....
def s:SysList(cmd: string): string
if exists('*systemlist')
return systemlist(cmd)
endif
return split(system(cmd), '\n')
enddef
function EnhancedDiff#Diff(...) *#{{{2*
let cmd = (exists("a:1") ? a:1 : '')
let arg = (exists("a:2") ? a:2 : '')
" no-op
" error occured, reset diffexpr
try
call s:DiffInit(cmd, arg)
catch
set diffexpr=
" call s:Warn( cmd . ' not found in path, aborting!' )
call s:Warn( ' not found in path, aborting ' )
return
endtry
....
Meanwhile this fix, script still
often gives an *error E97 cannot create diffs* when
I launch *:EnhancedDiff patience*
