Can't use an old expression in After effects 2022

[Jose21792375i4hy]

I used this code a while ago with Ae2019

Now I'm trying to use in Ae2022 but it says "Couldn't turn result into numeric value"
What do I need to change?

This is the expression:

(line with error angle=controlAngle+offset;)

layerCount=thisComp.numbLayers;
objectCount=layerCount-thisComp.layer("Control").index;
objectIndex=index-thisComp.layer("Control").index;

radius=thisComp.layer("Control").effect("Radius")("Slider");
controlAngle=thisComp.layer("Control").effect("Caroussel Angle")("Angle");
offset=360/(objectCount)*objectIndex;
angle=controlAngle+offset;

x=radius*Math.cos(degreesToRadians(angle))
y=0;
z=radius*Math.sin(degreesToRadians(angle))
centre=thisComp.layer("Control").toWorld([0,0,0]);
add(centre,[x,y,z])

For starters, the first line should be:

layerCount = thisComp.numLayers;

It's difficult to see without the fullo comp and Dan's right about the error in line 1, although that doesn't explain the issue wit the line:

angle=controlAngle+offset;

Has your project reverted to Legacy ExtendScript?  You can check this in File > project settings

When I'm debugging expressions, I'll create a text layer and add each line in turn to the sourcetext.  The error is suggest AE cannot get a number, so see what the code is failing to turn into a number.
