Class: ServiceUnavailableError

Defined in: src/types/errors.ts:654

Service unavailable error.

Remarks​

Thrown when a required service is not configured or not available. Maps to HTTP 503 Service Unavailable.

Example​

if (!discoveryService) {
  throw new ServiceUnavailableError('Discovery service not available');
}

Extends​

Constructors​

new ServiceUnavailableError()​

new ServiceUnavailableError(message, service?, cause?): ServiceUnavailableError

Defined in: src/types/errors.ts:669

Creates a new ServiceUnavailableError.

Parameters​

message​

string

Description of the unavailability

service?​

string

Name of the unavailable service

cause?​

Error

Original error (if chained)

Returns​

ServiceUnavailableError

Overrides​

ChiveError.constructor

Properties​

cause?​

readonly optional cause: Error

Defined in: src/types/errors.ts:71

Original error that caused this error (if any).

Remarks​

Error chaining allows tracking the full error context through multiple layers of the application. Useful for debugging complex error scenarios.

Example​

try {
  await fetchData();
} catch (err) {
  throw new ValidationError('Failed to validate data', 'field', 'required', err as Error);
}

Inherited from​

ChiveError.cause

code​

readonly code: "SERVICE_UNAVAILABLE" = 'SERVICE_UNAVAILABLE'

Defined in: src/types/errors.ts:655

Machine-readable error code.

Remarks​

Error codes are unique identifiers for error types, enabling programmatic error handling (switch statements, error maps), error tracking in monitoring systems, and client-side error translation (i18n).

Overrides​

ChiveError.code

service?​

readonly optional service: string

Defined in: src/types/errors.ts:660

Name of the unavailable service.

stack?​

optional stack: string

Defined in: node_modules/.pnpm/typescript@5.5.4/node_modules/typescript/lib/lib.es5.d.ts:1078

Inherited from​

ChiveError.stack

stackTraceLimit​

static stackTraceLimit: number

Defined in: node_modules/.pnpm/@types+node@24.10.1/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.

ChiveError.stackTraceLimit

Methods​

captureStackTrace()​

static captureStackTrace(targetObject, constructorOpt?): void

Defined in: node_modules/.pnpm/@types+node@24.10.1/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​

object
