Oops, my mistake.

Could you please share your mistake @tlbtlbtlb ? That would be helpful to others that get the same error.

@tlbtlbtlb What was the solution to this error? I am getting the same error. Thanks.

"Oops, my mistake" - That helped me solve the problem too, thanks for elaborating.

[samhmills]

@tlbtlbtlb would you still care to elaborate? Thanks

Edit: I solved my problem by wrapping my async function within an anonymous function:

async.parallel([ function(callback) {
    self.queues["genetic"].destroy(callback);
}

May not solve your specific issue but it solved mine!

[tlbtlbtlb]

async.parallel takes an array of functions. I was calling it like async.each.

How to solve TypeError: wrapAsync(...) is not a function

You're passing an undefined function as an iteratee, e.g. async.map(array, undefined, callback). Check your code in the call stack.
