Arrayindexoutofboundsexception: 55 Error, no idea what's gone wrong

Hi, does anyone know how to fix this error, my sketch works when I use a different svg file but not on other svg files. I can’t work out what might be causing this? This is the error that comes up : arrayindexoutofboundsexception: 55

    // Open whatever port is the one you're using.
    String portName = Serial.list()[1];
    myPort = new Serial(this, portName, 9600);
    grp = RG.loadShape("E.svg");
    grp.centerIn(g, 100, 1, 1);
    pointPaths = grp.getPointsInPaths();

       loadShape("E.svg").disableStyle();  // Ignore the colors in the SVG
  fill(255);    // Set the SVG fill to blue

       for(int i = 0; i < player.bufferSize() - 1; i++)
      float Random_var=(float(inString)/400)*50;
      for(int i = 0; i<pointPaths.length; i++){

    if (pointPaths[i] != null) {
     for(int j = 0; j<pointPaths[i].length; j++){
        vertex(pointPaths[i][j].x, pointPaths[i][j].y);
  void serialEvent(Serial p) {

Could you expand on this?

In addition to that, try to break down your problem into smaller pieces.

In a situation like this, I like to comment out blocks of code until it works again, and then, little by little, re-introduce code until it breaks again.

Hmm, so you are getting an Array Index out of Bound error, meaning that somewhere in your code, you are trying to reference an Array Index, that is too big (or small) (and hence doesn’t exist).

I don’t have Arduino so forgive me for not actually running your code to see exactly what is wrong, but I know that usually these out of bound errors usually happen in for loops because you end up referencing an index that is too high. I would advise you look here:

for(int i = 0; i < player.bufferSize() - 1; i++)


for(int i = 0; i<pointPaths.length; i++){

And here:

for (int j = 0; j<pointPaths[i].length; j++){
        vertex(pointPaths[i][j].x, pointPaths[i][j].y);

Again, I do not know exactly which line of code is giving you your error, I believe it is on line 55 though, but I do not think that is exactly where your error originated from. So again, I would say to first look at your for loops that are iterating through your arrays, and make sure you aren’t going overboard.

Secondly, I would look at any place that you assign anything to an array, such as:

vertex(pointPaths[i][j].x, pointPaths[i][j].y);

Or here:

if (pointPaths[i] != null) {

And see if you can find it. Hopefully that can get you started on fixing this problem, and if not, we wouldn’t mind helping out further.
