Class: PauseAnswerRequiredError

Defined in: src/core/pause.ts:260

Raised when an askHuman() / pauseHere() pause is resumed with NO answer.

That pause exists to collect a value, and the value it collects becomes the paused tool's result — the model reads it as what the tool said. Resuming with nothing has two live readings, "the person gave no answer" and "just carry on", and they produce different conversations. So the caller says which; the library does not choose.

Until 8.18.0 it chose, and chose invisibly: the missing answer became a role: 'tool' message with content: undefined, and the run died on the next turn inside the messages slot with a TypeError that named neither the tool nor the resume.

Nothing ran before this raised and the checkpoint is unchanged — answer it and resume the same checkpoint again.

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.

toolCallId

readonly toolCallId: string

The tool call id the pause is filed under.

toolName

The tool whose execute() paused.

Methods

captureStackTrace()

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();
