TypeError: Cannot read properties of undefined (reading 'array')

Hello, I'm using the example https://codesandbox.io/s/mlgzsc, and I just changed the loaded glb file from the rabbit to my own model. However, the program is reporting an error as shown in the title. What should I do?

Here is the vertex and normal output of my model

Normals:
BufferAttribute {isBufferAttribute: true, name: "", array: Float32Array, itemSize: 3, count: 233893…}
isBufferAttribute: true
name: ""
array: Float32Array
itemSize: 3
count: 233893
normalized: false
usage: 35044
updateRange: Object
version: 0
: "BufferAttribute"

Vertices:
BufferAttribute {isBufferAttribute: true, name: "", array: Float32Array, itemSize: 3, count: 233893…}
isBufferAttribute: true
name: ""
array: Float32Array
itemSize: 3
count: 233893
normalized: false
usage: 35044
updateRange: Object
version: 0
: "BufferAttribute"

@KIC-Crack Faced the same error last week when I loaded a model that didn't have attributes.uv, which the underlying library is explicitly looking for.

A workaround for me was to populate attributes.uv with an empty array after load:

geometry.setAttribute('uv', new BufferAttribute(new Float32Array([]), 1))

`try
{
const evaluator = new Evaluator();
const resultGeometry = evaluator.evaluate(terrainBrush, pondBrush, SUBTRACTION);

            if (resultGeometry?.attributes?.position) 
            {
                resultMesh = new THREE.Mesh(resultGeometry, new THREE.MeshStandardMaterial({ color: 0x8B4513 }));
                scene.add(resultMesh);
            }
            else 
            {
                console.error("❌ Resulting geometry is invalid!", resultGeometry);
            }
        }
        catch (error) 
        {
            console.error("❌ CSG evaluation error:", error);
        }`

For me the same error is at the evaluate function which in turn requires array attribute which it seems cannot read, both the brushes need the attribute, first brush is reference geometry and second brush is target geometry, how to solve this problem
