Class: ConfigError

Defined in: src/core/errors/config-error.ts:72

Error subclass for configuration failures.

Failure Mode

Invalid config file — YAML/JSON parse error or Zod schema validation failure

Failure Mode

Missing config — no praman.config.ts/yml found in project root

Failure Mode

Schema validation — config values out of range or wrong type

Example

const error = new ConfigError({
message: 'Invalid auth strategy',
attempted: 'Validate config',
validationErrors: [{ path: ['auth'], message: 'Invalid', code: 'invalid_enum_value' }],
});

Constructors

Constructor

new ConfigError(options): ConfigError

Defined in: src/core/errors/config-error.ts:93

Creates a new ConfigError instance.

Parameters

options

ConfigErrorOptions

Config error construction options including validation errors and config path.

Returns

ConfigError

Example

message: 'Config file contains invalid values',
attempted: 'Load config from praman.config.ts',

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/config-error.ts:144

Returns structured context for AI agents with configuration diagnostics.

Returns

AIErrorContext & object

Base AI context plus validationErrors and configPath fields to help diagnose configuration issues and suggest fixes.

Example

const context = error.toAIContext();
// context.validationErrors, context.configPath available
// Send to LLM for config fix suggestions

Overrides

PramanError.toAIContext


toJSON()

toJSON(): SerializedPramanError & object

Defined in: src/core/errors/config-error.ts:120

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

Returns

SerializedPramanError & object

Base fields plus validationErrors and configPath.

Example

const json = error.toJSON();
// json.configPath === '/app/praman.config.ts'
// json.validationErrors === [{ path: ['auth'], message: 'Required', code: 'invalid_type' }]

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
