Unable to find matching buffer file

An error occurred while trying to import the model file. Error message: unable to find matching buffer file.

I exported my decimated blender file per Pieter’s webinar link https://blog.enscape3d.com/content-hub/webinars/building-a-custom-asset-library-with-blender?access=8edff9308ee989607ec0d67392abacbe

Nonetheless, at only 3kb I can’t help but think something failed in the export from Blender. I can’t find anything on this please help!
