Error - json encoding error: Object of type builtin_function_or_method is not JSON serializable

[TechSavage1989]

I'm getting the below error. I don't know what script/macro config is causing it, but it does not occur when I don't include the macros in my printer.cfg.

Also, the behavior is such that if I firmware restart, everything will work until I refresh the browser page, or open the UI on another machine/browser. At that time the printer crashes and this error reports.

I'm using Fluidd and have the latest release of Klipper and these macros.

Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
