Class: RunInFlightError

Thrown when run() / resume() is called on a runner that is already running.

One instance answers one turn at a time. To run two turns at once, build two agents — a chart is built once per instance and instances are cheap — or put the turns behind standingAgent({ onConcurrentInvoke: 'enqueue' }), which queues them.

Example

// Refused: both would write the same instance's last-run state.
await Promise.all([agent.run({ message: 'a' }), agent.run({ message: 'b' })]);

// Fine: two instances, two sets of state.
await Promise.all([agentA.run({ message: 'a' }), agentB.run({ message: 'b' })]);

Properties

activeRunId

readonly activeRunId: string

The run already in flight, so a log line can be joined to its trace.

agentId

readonly agentId: string

Defined in: src/core/conversation.ts:61

The runner that is busy, by its configured id.

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()

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();

static prepareStackTrace(err, stackTraces): any
