The geometry is invalid:

WARNING| resetting parameter vlist on X (found: nans or infs)			
vlist is the list of vertices. Some vertex coordinates are not a number or infinite values, so Arnold resets the list of vertices, and then there are no vertices.

Here's a similar issue: https://answers.arnoldrenderer.com/questions/18550/degenerate-polygon-objects-found-in-frame-x-error...

The user had to add a clean node in Houdini to delete the invalid values and reexport the alembic file.
