Hi there, I've got an error. after running node 1.save-roads-graph.js data/bellevue.json an error occurs which is:


Error: Invalid JSON (Unexpected "ÿ" at position 0 in state STOP)
    at Parser.proto.charError (file_address\node_modules\jsonparse\jsonparse.js:90:16)
    at Parser.proto.write (file_address\node_modules\jsonparse\jsonparse.js:154:23)

how can I overcome this error?

I solved it with copy and pasting the json file into another json file. I do not know why, but somehow the renderer could not render the json file after exporting the city json file. My guess is that it's because of memory problem.
