declaration

Thrown when an item that should be added to the cart has a quantity error.

Quantity errors may be:

MINIMUM_NOT_MET: The quantity is less than the minimum order quantity.
MAXIMUM_EXCEEDED: The quantity is greater than the maximum allowed quantity.
INVALID_INCREMENT: The quantity is not a valid increment.

Properties

Property	Type	Default value	Description
`cause?`	`unknown`	`undefined`	Represents the underlying cause or source of the error.
`code?`	`null` \| `string` \| `number`	`undefined`	A unique identifier for the error, which can be a short uppercase string or a numeric code.
`data`	{ `reason`: `ProductQuantityErrorReason`; `variantId`: `string`; }	`undefined`	Additional data associated with the error. This property can hold unstructured information or supplementary details that provide context to the error.
`data.reason`	`ProductQuantityErrorReason`	`undefined`	‐
`data.variantId`	`string`	`undefined`	‐
`expose?`	`boolean`	`undefined`	Determines whether the error message can be safely exposed externally.
`logLevel?`	`string` \| `number`	`undefined`	Specifies the log level at which this error should be recorded.
`logMessage?`	`boolean`	`undefined`	Indicates whether the error should be logged in the application's logs.
`message`	`string`	`undefined`	‐
`name`	`string`	`undefined`	‐
`stack?`	`string`	`undefined`	‐
`code`	`"CART_PRODUCT_QUANTITY_ERROR"`	`'CART_PRODUCT_QUANTITY_ERROR'`	‐
`stackTraceLimit`	`number`	`undefined`	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.

Methods

captureStackTrace()

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

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;
}

a();
