Class: SchemaMismatchError

Defined in: src/core/errors/schemaMismatchError.ts:17

Stable

The request succeeded, but the response is not what the endpoint's schema describes.

Covers both ways that can happen: the response was not JSON at all, or it parsed as JSON and its shape had drifted. The two are told apart by cause — a validation failure carries the underlying ZodError, a non-JSON response carries nothing — while body holds what actually arrived either way.

They are one error rather than two on purpose: from a caller's side both mean "the API answered 2xx and the value cannot be trusted", and nobody should have to know which validator this library uses in order to catch that.

Distinct from ApiError, which means the request itself failed.

stackTraceLimit

static stackTraceLimit: number;

Defined in: node_modules/.pnpm/@types+node@22.20.1/node_modules/@types/node/globals.d.ts:68

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()

static captureStackTrace(targetObject, constructorOpt?): void;

Defined in: node_modules/.pnpm/@types+node@22.20.1/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;
}

a();

Parameters

Parameter	Type
targetObject	object
constructorOpt?	Function
