Build LLM-powered agents
with production-ready TypeScript

DSPy for TypeScript. Working with LLMs is complex—they don't always do what you want. DSPy makes it easier to build amazing things with LLMs. Just define your inputs and outputs (signature) and an efficient prompt is auto-generated and used. Connect together various signatures to build complex systems and workflows using LLMs.

AxMediaNotSupportedError

Defined in: https://github.com/ax-llm/ax/blob/9a5a7060a48f9eef46efc680b0cdf6b42bff5df2/src/ax/util/apicall.ts#L303

Error thrown when an AI provider doesn’t support a required media type.

This error is thrown during content processing when a provider cannot handle a specific media type and no suitable fallback mechanism is available or configured.

Example

try {
  await textOnlyProvider.chat(imageRequest);
} catch (error) {
  if (error instanceof AxMediaNotSupportedError) {
    console.log(`${error.mediaType} not supported by ${error.provider}`);
    if (error.fallbackAvailable) {
      console.log('Consider using content processing services');
    }
  }
}

stackTraceLimitstaticnumberundefinedThe 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.Error.stackTraceLimit

Methods

toString()

toString(): string;

Defined in: https://github.com/ax-llm/ax/blob/9a5a7060a48f9eef46efc680b0cdf6b42bff5df2/src/ax/util/apicall.ts#L329

Returns a string representation of an object.

Returns

string


captureStackTrace()

static captureStackTrace(targetObject: object, constructorOpt?: Function): void;

Defined in: node_modules/@types/node/globals.d.ts:145

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;
}
