This error indicates that you have provided the wrong number of arguments to a component of
parallelReduce. Please refer to the documentation for the specific component you
are trying to use.
For example, the code below erroneously supplies a closure as the second argument to
timeRemaining is a shorthand for a timeout which automatically publishes and returns the
parallelReduce accumulator. The component only expects one argument. You can fix this code by removing
the second argument supplied.
