Why passing NULL here instead of initializing the exception to NULL and passing the reference like you did below?

Because exception is not evaluated resp. used further here.

I think it should though - any exception handling can be useful

But how?
Handling it like in arrayBuffer via KrollPromise then it would make toArrayBuffer and arrayBuffer redundant.
Handling it with the JavaScriptCore API (I am not familiar with it), ChatGPT suggests the following:
if (exception) {
JSStringRef exceptionStr = JSValueToStringCopy(context.JSGlobalContextRef, exception, NULL);
NSString *message = (__bridge_transfer NSString *)JSStringCopyCFString(kCFAllocatorDefault, exceptionStr);
JSStringRelease(exceptionStr);
// e.g. handle message
free(arrayBytes);
return nil;
}

Mhh, we are there even both then, if the only difference is the exception?

Oh, there is still a difference – a different context may be used (JSContext.currentContext vs. [self currentContext]).
