Parsing and Reading Serial JSON data

Processing Electronics (Arduino, etc.)
1

Hi,

I’m trying to send serial JSON data from an Arduino to Processing. I found documentation on reading JSON data from a file, but I’d like to read the JSON data from a Serial input. I tried the following code:

val = myPort.readString(); 
  
  if (val != null) {
    data = loadJSONObject(val);
}

However, with the above code I get the error:

The file is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.

How can I parse Serial JSON data? Any help would be greatly appreciated.
