power-manager suspend when power button is pressed


I'm running XFCE on a Chromebook and trying to set XFCE to suspend when the power button is pressed. I've set this option in Power Manager. I've also set the display to switch off when the lid is closed:

When I press the power button, it doesn't suspend, instead displaying this error:
power manager
launch helper exited with unknown return code 1

I've tried running with debug:

sudo xfce4-power-manager --debug --no-daemon

closing the lid (does work - switches off the display):

TRACE[xfpm-manager.c:439] xfpm_manager_lid_changed_cb(): LID close event: ((XfpmLidTriggerAction) LID_TRIGGER_NOTHING)
TRACE[xfpm-dpms.c:284] xfpm_dpms_force_level(): start
TRACE[xfpm-dpms.c:303] xfpm_dpms_force_level(): Forcing DPMS mode 3

opening lid:

TRACE[xfpm-manager.c:472] xfpm_manager_lid_changed_cb(): LID opened: ((XfpmLidTriggerAction) LID_TRIGGER_NOTHING)

pressing the power button (fails to suspend XFCE):

TRACE[xfpm-button.c:118] xfpm_button_filter_x_events(): Key press: ((XfpmButtonKey) BUTTON_POWER_OFF)

XFCE has been fantastic and this forum has been very helpful for me to be able to troubleshoot. I'm hoping you can assist with the solution.
