Error with gr_modtool makexml howto_detect_ff

I am working to make a detector block in gnuradio 3.6.5.1 using gr-how
“out-of-tree module”. I am stuck with an error during " gr_modtool
makexml howto_detect_ff " command.

GNU Radio module name identified: howto
Warning: This is an experimental feature. Don’t expect any magic.
