AxContentProcessingError

Defined in: https://github.com/ax-llm/ax/blob/5b28f9093bb70863b59459bb6df5062d005bce41/src/ax/util/apicall.ts#L456

Error thrown when content processing/transformation fails.

This error wraps underlying failures from content processing services like image-to-text, audio transcription, file text extraction, or URL content fetching. It provides context about what type of content was being processed and at which step.

Example

try {
  await axProcessContentForProvider(content, provider, {
    imageToText: imageService.analyze
  });
} catch (error) {
  if (error instanceof AxContentProcessingError) {
    console.log(`Failed processing ${error.contentType} during ${error.processingStep}`);
    console.log('Original error:', error.originalError.message);
  }
}

Properties

Methods

toString()

toString(): string;

Defined in: https://github.com/ax-llm/ax/blob/5b28f9093bb70863b59459bb6df5062d005bce41/src/ax/util/apicall.ts#L482

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;
}

a();
