Error thrown when SDK configuration is invalid

This error is used during SDK initialization when configuration parameters are missing, malformed, or incompatible. It helps users identify and fix configuration issues quickly.

Examples

Invalid configuration

throw new ConfigurationError(
  'Invalid timeout value: must be between 1000 and 300000',
  'timeout'
);

Catching configuration errors

try {
  const sdk = new LaunchpadSDK(config);
} catch (error) {
  if (error instanceof ConfigurationError) {
    console.log(`Fix config field: ${error.field}`);
    console.log(`Issue: ${error.message}`);
  }
}

Property	Modifier	Type	Description	Inherited from
field?	public	string	-	-
message	public	string	-	Error.message
name	public	string	-	Error.name
stack?	public	string	-	Error.stack
stackTraceLimit	static	number	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.	Error.stackTraceLimit

Methods

captureStackTrace()

static captureStackTrace(targetObject, constructorOpt?): void

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();
