[BUG] panelize process error

[Uvis-Acurable]

When running panelize to generate the panel for the board it returns error: "An error occurred: argument 3: TypeError: wrong type", that essentially comes from subprocess from kiplot.py, however I can't see anything wrong with the arguments.

This used to work, but there have been changes to multiple things, OS upgrades docker updates, different version of KiBot

**Environment:

• Mac M2 Pro, Sonoma 14.4
• Docker v4.34.2 (updated from 4.32)
• KiCad v8.0.4
• Tried 2 images: kicad8_auto:1.8.1-1_k8.0.4_d12.1 and kicad8_auto:1.7.0

DEBUG:- Output from command: An error occurred: argument 3: TypeError: wrong type

Note that this is an error from KiKit. When you find an issue related to KiKit you should add:

    "debug": {
        "trace": true
    }

To your KiKit config. For some reason that I don't understand this isn't the default. Once you do it you'll find the real place where the problem is:

An error occurred: argument 3: TypeError: wrong type
No output files produced
Traceback (most recent call last):

So this seems to be a compatibility issue with the Shapely installed in the docker image, triggered by the use of the tightframe. I'll try to find the exact solution.

[set-soft]

I don't see a simple solution, you could try to just use pip to install shapely. Lamentably this is a very problematic package and the feature you want to use needs a version that isn't available for Debian stable.

[set-soft]

Hi @Uvis-Acurable !

I added a really ugly installation of Shapely to the current images, please try pulling a fresh ghcr.io/inti-cmnb/kicad_auto_full:dev_k8 and tell me if it works for your PCB.

[Uvis-Acurable]

Hi @set-soft I will try this and let you know

[Uvis-Acurable]

I am still getting the same error. Now when I enabled the trace I am getting the same output as you

[set-soft]

Are you sure you pulled a fresh docker image of ghcr.io/inti-cmnb/kicad_auto_full:dev_k8? Try running this in the docker image:

python3 -c "import shapely; print(shapely.__version__)"

You should get 2.0.6, if you get 1.8.5 then this is not a fresh image.

[Uvis-Acurable]

It reports V1.8.5 However the image I pulled is: ghcr.io/inti-cmnb/kicad_auto_full:dev_k8_1.8.2-b077362_k8.0.4_d_sid_b3.5.1

[set-soft]

Ok, try it again, should be dev_1.8.2-ed9644c_k8.0.4_d_sid_b3.5.1 or newer

[Uvis-Acurable]

Still Getting the same:

% docker run --rm -it -v$(pwd):/workdir -entrypoint=/bin/bash --platform linux/amd64 ghcr.io/inti-cmnb/kicad_auto_full:dev_k6_1.8.2-ed9644c_k6.0.11_d12.1_b3.5.1
root@0ebcb4546285:/# python3 -c "import shapely; print(shapely.__version__)"
1.8.5
root@0ebcb4546285:/#

[set-soft]

You are pulling a KiCad 6 docker image, KiKit doesn't support KiCad 6. The KiCad 7 and 8 got Shapely 2.0.6.

My bad. It works now. Builds the panel as expected.
