Thought Process +I see the issue. The code is trying to set `rep_bone.bone.select = True`, but in Blender the correct attribute is on the `Bone` object accessed via `bone` property. The issue is that `rep_bone` is a `PoseBone`, and `rep_bone.bone` is the `Bone` object. The `select` property should be on `rep_bone.bone.select`. + +Wait, actually the error says "'Bone' object has no attribute 'select'". This is odd because `bpy.types.Bone` does have a `select` property in pose mode. + +Actually, looking more carefully - in Blender 5.0, you need to be in pose mode for `bone.select` to work, and the bone needs to be visible/selectable. But the error message suggests the attribute doesn't exist at all. + +Let me check if there's something else going on. Maybe we should wrap this in a try/except or use a different method to select bones. Actually, for the visual transform apply, we might not need to select bones at all - the operator works on selected bones, but we could use `pose.bones.active` instead or just skip selection if it fails. + +Let me add error handling around the bone selection:Actually, let me also check the bake function for the same issue:
