Grasshopper for rhino question

This error message comes up when I try to create a site map using grasshopper. I am currently using Urbano I have been using it for a while now however I am trying something different in terms of file types, instead of using a OSM file I am using a PBF file for a much larger area. This error message keeps coming up and I do not know how to convert the PBF file to OSM. or is there another way.

  1. Solution exception:‘.’, hexadecimal value 0x00, is an invalid character. Line 1, position 1.
