How to fix: Unsupported GLTF extension

Extension can’t be validated as it is not supported by the validator. Make sure your model passes GLTF validator.

One or more of your products has a 3D model with an unsupported extension. Make sure that your 3D model you have provided to the 3D model link [virtual_model_link] attribute is in the right format. These are the file formats supported by GLTF validator: GLTF (.gltf), and GLB (.glb). We also recommend you to test your 3D model using the Modelviewer tool.

If you provide a 3D model in an unsupported format, it will be disapproved and the product will be displayed without the 3D model.
