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.

PramanError.stackTraceLimit

Methods​

toAIContext()​

toAIContext(): AIErrorContext & object

Defined in: src/core/errors/auth-error.ts:139

Returns structured context for AI agents with authentication diagnostics.

Returns​

AIErrorContext & object

Base AI context plus strategy and loginUrl fields to help diagnose authentication configuration issues.

Example​

const context = error.toAIContext();
// context.strategy, context.loginUrl available
// Send to LLM for auth troubleshooting suggestions

Overrides​

PramanError.toAIContext

toJSON()​

toJSON(): SerializedPramanError & object

Defined in: src/core/errors/auth-error.ts:115

Serializes the error to a JSON-safe object with authentication fields.

Returns​

SerializedPramanError & object

Base fields plus strategy and loginUrl.

Example​

const json = error.toJSON();
// json.strategy === 'btp-saml'
// json.loginUrl === 'https://accounts.sap.com/login'

Overrides​

PramanError.toJSON

toUserMessage()​

toUserMessage(): string

Defined in: src/core/errors/base.ts:180

Formats the error for human-readable console output.

Returns​

string

Multi-line formatted string with all diagnostic sections.

Example​

console.error(error.toUserMessage());

Inherited from​

PramanError.toUserMessage

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();

Parameters​

targetObject​

object

constructorOpt?​

Function

Returns​

void

Defined in: node_modules/@types/node/globals.d.ts:55
