AuthUnavailableError

Defined in: src/http/unauthorized.ts:118

An authenticator could not answer. Not a rejection.

“The credential is bad” and “I could not find out whether the credential is bad” are different answers, and collapsing them is expensive in both directions. A sidecar restart that surfaces as 401 makes every caller re-authenticate at once; the DuckDB extension treats a second 401 after a refresh as fatal, so a thirty-second blip becomes a fleet-wide re-login storm. And a caller that negative-caches a rejection will cache an outage.

Deliberately not an AuthFailure, which is the whole point: chainAuthenticate advances to the next authenticator on a credential rejection, so an outage raised as one is read as “this credential isn’t mine, try the next” and ends up as a 401 from the end of the chain. Raised as this type it propagates, and the handler renders 503 with Retry-After instead.

Throw it for transport failures, timeouts, and 5xx from a remote authority. Do not throw it for a credential the authority answered about.

readonly detail: string;

Defined in: src/http/unauthorized.ts:123

Operator-facing text. Must not contain the credential.

retryAfter

readonly retryAfter: number;

Defined in: src/http/unauthorized.ts:121

Seconds to advertise in Retry-After. A hint to retry, not a backoff schedule — keep it short.

stackTraceLimit

static stackTraceLimit: number;

Defined in: node_modules/@types/node/globals.d.ts:67

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()

Call Signature

static captureStackTrace(targetObject, constructorOpt?): void;

Defined in: node_modules/@types/node/globals.d.ts:51

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();
