Class: SubUnitQuantityMismatchError

Defined in: shared/pricing/sub-units.ts:123

Thrown when a consumer-supplied getQuantity resolves to a different count than the consumer-supplied (or default) enumerateSubUnits for the same line. The two must agree: quantity drives base-price scaling, sub-units drive qualifying scaling, and a divergence means a misconfiguration that would silently produce wrong totals.

quantity is the count the CALCULATOR will charge for, so on a line whose base rule declares a duration axis (per) it is the PRODUCT of both axes — getQuantity(line, pricing_unit) × getQuantity(line, per) — not either axis alone. durationAxis records which second axis was folded in, so the message can say where a two-axis expectation came from; undefined on the single-axis lines that are the overwhelming majority.

The Error.stackTraceLimit property specifies the number of stack frames collected by a stack trace (whether generated by new Error().stack or Error.captureStackTrace(obj)).

The default value is 10 but may be set to any valid JavaScript number. Changes will affect any stack trace captured after the value has been changed.

If set to a non-number value, or set to a negative number, stack traces will not capture any frames.

captureStackTrace()Copy Anchor Link

static captureStackTrace(targetObject: object, constructorOpt?: Function): void;

Defined in: ../node_modules/.pnpm/@types+node@24.13.3/node_modules/@types/node/globals.d.ts:52

Creates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called.

const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack;  // Similar to `new Error().stack`

The first line of the trace will be prefixed with ${myObject.name}: ${myObject.message}.

The optional constructorOpt argument accepts a function. If given, all frames above constructorOpt, including constructorOpt, will be omitted from the generated stack trace.

The constructorOpt argument is useful for hiding implementation details of error generation from the user. For instance:

function a() {
  b();
}

function b() {
  c();
}

function c() {
  // Create an error without stack trace to avoid calculating the stack trace twice.
  const { stackTraceLimit } = Error;
  Error.stackTraceLimit = 0;
  const error = new Error();
  Error.stackTraceLimit = stackTraceLimit;

  // Capture the stack trace above function b
  Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
  throw error;
}
