On line 19 you are reading directly from path using File which assumes a local file. You need to use the text property of the WWW object instead to get the text returned by the server.

You also will probably want to check the error property of the WWW object as well, in case there are errors making the web request.

changed line 19 to
JSONstring = File.ReadAllText (www.text);:wink:

getting path contains invalid char error

It should be:
JSONstring = www.text;

File.ReadAllText tries to read all the text in the file you give it. You’re sending in a JSON representation of a creature.

A creature is not a file!
