Class: UndecomposedDurationAxisError

Defined in: shared/pricing/qualify.ts:56

Thrown when a line's base price declares a duration axis (per), the line did NOT decompose into per-period sub-units, and a matched rule's qualification genuinely varies per sub-unit.

Why this exists again after PLA-280Copy Anchor Link

PLA-280 taught the enumerator to decompose two-axis lines, and this guard was deleted on the reasoning that its case could no longer arise. That was wrong — review found several paths where two-axis decomposition legitimately bails, and each one lands back on a single atomic sub-unit:

• no line range whose fields match every varying condition, leaving no safe span to step.
• a billed duration count that disagrees with that range's step count.
• a NON-INTEGER axis. A 2.5-hour booking cannot be partitioned into whole sub-units whose count equals the billed quantity.
• a product over MAX_TWO_AXIS_SUB_UNITS.
• a consumer enumerateSubUnits whose count disagrees with the billed product, or whose two-axis date-varying sub-units lack valid UTC anchors.

With one sub-unit, any qualification is wrong: resolveScalingQuantity reads total_sub_units === 1 as "scale by the line's real quantity" and bills the FULL two-axis product, and the percentage branch's ratio resolves to 1/1. That is the original overcharge, so this refuses the quote instead — a misconfiguration that inflates prices is worse than no quote.

Note it is broader than the pre-PLA-280 version, which only fired for a method: "flat", scaling: "per_unit" action and therefore never covered the percentage shape at all. Reaching this point already means the rule varies per sub-unit, which makes ANY emitted qualification wrong regardless of action shape — so the action check was never the right discriminator.

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.

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;
}
