Aux mixer not loading

I am trying to build an aux mixer to send basic throttle to AUX 1. I successfully run the configuration by making changes to pass.aux.mix. I then copied and renamed the configuration to reaper.aux.mix. When I run my configuration script calling on the reaper.aux.mix, it does not load /dev/pwm_outputs1 or the aux mixer.

Here is the successful output:

Here is the output of running the new file, reaper.aux.mix which is a copy of pass.aux.mix

I change
set MIXER_AUX pass
to
set MIXER_AUX reaper
and receive the later results…

EDIT: Found the mixer file was not being formatted correctly, by checking the /etc/mixers folder

hi how did you get the debug information in NSH?
you used USB or FDTI or others?
