Problem Statement/Rationale

In the aggregation builder the template for a $sortByCount stage is:

/**
 * expression: Grouping expression or string.
 */
{
  expression
}

the braces are invalid a valid stage is:

{$sortByCount: "$fieldName"}

so the template should be:

/**
 * expression: Grouping expression or string.
 */
  expression
