Error on post-process (estimate working fine)

[jankolkmeier]

Whenever I run klipper_estimator in post-process mode, I get the following error:

>>> .\klipper_estimator.exe --config_moonraker_url http://ratos.local post-process SmallCube.gcode
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', tool/src/cmd/post_process.rs:289:47
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I've tried a number of different g-code files, both with v1.0.0 and v1.1.0, and I've tried both on Windows (klipper_estimator.exe) and on my RPI (klipper_estimator_rpi). Running estimate returns the expected result (see below).

• Slicer: SuperSlicer 2.3.57
• OS: Windows 10 / RatOS (a MainsailOS flavor)
• Klipper: v0.10.0-225-g6e6ad7b5
• Moonraker: v0.7.1-285-g505c1bf

Sample of a gcode file that failed for me.

Not sure if relevant, but here is the result of dump_config:

This is caused by firmware_retraction so yes the config was very helpful 😊

Thanks for reporting this. New version is going up with this fixed.
