Hello! I am trying to use the getPath() function on an EventDescription and am getting back an empty string in the `val` with no error from the function (FMOD.OK is returned). Here is the relevant block of code:

```auto
var path = {}, size = 0, retrieve = 0;
result = description.val.getPath(path, size, retrieve)
CHECK_RESULT(result, 'getPath() call failed for event instance');

if (!path.val){
	console.log('Fmod Callback could not find description of event for event instance');
}

```

And here is the CHECK\_RESULT block:

```auto
	static CHECK_RESULT(result, message='')
	{
		if (result != FMOD.OK)
		{
			if (message == ''){
				console.log(FMOD.ErrorString(result));
			} else {
				console.log(message + ': ' + FMOD.ErrorString(result));
			}
		}
	}

```

I will provide any other details to help diagnose this.

It looks like you are passing in a size of 0, which should cause an invalid parameter error to be returned. Can you try again with a larger size, say 256 for instance?

Also, be aware the strings bank must be loaded to get this information out.
