After Effects error: Unsafe Operation Attempted ( 58 :: 0 )
Keep getting this error in CS5 and can’t seem to isolate where it’s coming from or how to avoid it. End up having to force quit After Effects to get out of the error loop. Think it might have something to do with the sampleImage(); command but not sure.
Any help would be greatly appreciated!
timeEnabled = thisComp.layer("Controls").effect("Enable Time Offset")("Checkbox");
restartEnabled = thisComp.layer("Controls").effect("Restart Time")("Checkbox");frameOffset = thisComp.layer("Controls").effect("Frame Offset")("Slider");
if(timeEnabled > 0){
n = name.slice(2);
tile = thisComp.layer("m_" + n)
targetLayer =thisComp.layer("Controls").effect("Map")("Layer")
samplePoint = tile.transform.position
sampleRadius = [1,1];
above = false;if(restartEnabled>0){
for (f = timeToFrames(); f>= timeToFrames(inPoint); f--){
t = framesToTime(f);
sampledColor_8bpc = 255 * targetLayer.sampleImage(samplePoint, sampleRadius,true,t);
R = Math.round(sampledColor_8bpc[0]);if (R>1 ){
above = true; break;
}
}
}else{for (f = timeToFrames(inPoint); f<=timeToFrames(); f++){
t = framesToTime(f);
sampledColor_8bpc = 255 * targetLayer.sampleImage(samplePoint, sampleRadius,true,t);
R = Math.round(sampledColor_8bpc[0]);if (R==0){
t = t - framesToTime(1);
above = true; break;
}}
}if (above) time - t + framesToTime(frameOffset) else 0;
}else{
time;
}

What property is expression applied to? Is there any chance that the result of the expression changes the target layer?

Thanks for checking this out Dan. It’s applied to Time Remap. Unfortunately the comp that it’s referencing isn’t affected by the expression. Here’s a link to the file: https://dl.dropboxusercontent.com/u/1881942/Coke-TimeRemap-CC-v024.aep
Usually I can trigger the error loop by attempting to duplicate the comp in the project window.

I was able to reproduce the error in CS5. I don’t see anything obvious that could be causing it except maybe that there is a lot of expression crunching going on.
It does seem to work OK in CS6, so it may be a bug that was discovered and fixed. I don’t know what else to tell you.

Ok, thanks again for taking a look at it Dan.
