My Issue When trying to print or do a Bed Mesh Calibrate I get this error and can not continue.
Error evaluating ‘gcode_macro BED_MESH_CALIBRATE:gcode’: UndefinedError: ‘dict object’ has no attribute ‘polygon’
Actually, the error lies within this giant pile of lines:

The author should know what they have done here.
So how do I fix it again?
Talk to whoever wrote that giant pile of lines and tell them that it’s generating an error.
You might suggest that they replace
{% set all_points = printer.exclude_object.objects | map(attribute='polygon') | sum(start=[]) %}
with
{% set all_points = printer.exclude_object.objects | selectattr('polygon', 'defined') | map(attribute='polygon') | sum(start=[]) %}

Thank you for the advice.
Actually this is what wrote that pile of lines of course this did not get up Klipper Macro by GAB3D (gab-3d.com)dated with Klipper
Only trust a macro when you know how it works.
IMO it is a bit much to use some arbitrary macro generator and then expect the folks here to debug its questionable results
