Graphorin API reference / @graphorin/provider / / ProviderToolChoiceUnsupportedError

Class: ProviderToolChoiceUnsupportedError

Defined in: packages/provider/src/errors/errors.ts:329

Stable

The caller requested a forced toolChoice ('required' or { tool: name }) on an adapter whose wire protocol has no way to enforce it (the native Ollama /api/chat API has no tool_choice field). Thrown at request time instead of silently degrading the forced choice to 'auto' - a forced tool call is a contract, not a hint.

stackTraceLimit	static	number	undefined	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.	-	GraphorinProviderError.stackTraceLimit	node_modules/.pnpm/@types+node@22.19.17/node_modules/@types/node/globals.d.ts:68

Methods

captureStackTrace()

static captureStackTrace(targetObject, constructorOpt?): void;

Defined in: node_modules/.pnpm/@types+node@22.19.17/node_modules/@types/node/globals.d.ts:52

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();

Parameters
