Problem to create parameter templates in Inventree

[vutaf]

Hi,

I ran into a problem during the setup: the Inventree server is new installed, based on the current docker image, nothing customized. kintree is installed on a Win10 machine via pip, version is 1.1.0

PS C:\Users\XXXX> python --version
Python 3.11.9

when I start kintree.setup_inventree, I ran into following problem: (I added additional print in setup_inventree.py (line 46) to get the list of parameters at start, and in inventree_api.py to get the parameters of create_parameter_template() (line 825)) Also set SETUP_CATEGORIES to false, as it worked without problems

PS C:\Users\XXXX> python -m kintree.setup_inventree

For me, it looks like a problem with the encoding, but I'm running out of ideas where to look furter. Does someone have a hint?

Thanks a lot

yeah, that's an encoding issue. For a quick fix to get your setup up and running go to your local Ki-nTree config folder, open the user/parameters.yaml and replace/remove the units with special characters (should be only the ones with Ω). Even better if you could try to replace the file with this one here: parameters.yaml.txt (remove the .txt from the file name after downloading it) so I could directly test if the quick fix I have in mind works.

Just check, with your parameters.yaml the script is working. Thanks a lot :)

updated the parameters config file: https://github.com/sparkmicro/Ki-nTree/commit/49e07ae769dad850c7657a38b67fd8c1ff686bd9
