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' }],
});

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
import { ConfigError } from '#core/errors/config-error.js';
const error = new ConfigError({
message: 'Config file contains invalid values',
attempted: 'Load config from praman.config.ts',
configPath: '/app/praman.config.ts',

});

stackTraceLimit
staticstackTraceLimit: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.

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
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
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
captureStackTrace()
staticcaptureStackTrace(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();
