Texture bump issue in the Exported GLTF model.

Hi,
I am trying to export the model containing the texture and bump but only the texture is visible in the exported file, no bumps observed.
Please refer to the attachments of the exported file and the screen shot of the expected output.

Start by inspecting the linked exported file and comparing it with the expected-output screenshot; the issue does not identify the exporter, source asset, or repository entry point. Reproduce the export with texture and bump data, then trace the relevant material/export path. Done means the exported glTF displays the expected bump effect.
