Input ports

  Sends the parsed JSON content read from the file specified by path. Example: { "foo": 1, "bar": 2, "foobar": [1,2] }

• bounced: string

  Sends the path if the operation has failed. Example: "/home/user1/dir1/foo.json"

• error: {"error": string}

  Sends error information if the operation has failed. Example (file access error): { "error": "Error: ENOENT: no such file or directory, open '/home/user1/dir1/foo.txt'" } Example (json parse error): { "error": "SyntaxError: Unexpected token } in JSON at position 45" }
