Error after custom machine creation

[allard]

I've setup the distribution package, i'm able to build the default image, and have created a custom image that includes some additional recipes.

Now I want to continue with creating my custom machine. I've created a custom device tree with cubeMX and placed it in meta-st-stm32mp-addons/mx/<projectname>. I followed the steps https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machine

My .conf looks like this:

#@TYPE: Machine
#@NAME: stm32mp1-mx
#@DESCRIPTION: Configuration for STM32CubeMX generated project
#@NEEDED_BSPLAYERS: layers/meta-openembedded/meta-oe layers/meta-openembedded/meta-python

Now when I want to bit-bake my custom image OR the st-image-weston image the following error appears:

Any idea's? Did I miss a step?

Doing a clean seems to have resolved this error.
