i have a problem loading my 3d object (json file) in my 3d scene.

Hello friends,

i translate from german to english with google and hope you can understand me.

i have a problem loading my 3d object (json file) in my 3d scene.
have i not yet fully integrated my property?
I didn’t assign any textures.

i am an absolute beginner and just finished my basic javascript course a few days ago. I ask for understanding.
I’ve been working on the problem for about 15 days and can’t understand it.

My model was created from blender using three.js exporter and is also displayed in the editor of threejs.org/editor. unfortunately with strange textures.

The browser loads the file 100% but tells me 2 errors. I’m not sure about that either.

Thank you very much for your time.
