new CommandExitError(result): CommandExitError

Parameters ​

result ​

CommandResult

Returns ​

CommandExitError

Overrides ​

optional cause?: unknown

message ​

message: string

name ​

name: string

stack? ​

optional stack?: string

Inherited from ​

SandboxError.stack

stackTraceLimit ​

static stackTraceLimit: 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.

Accessors ​

error ​

Get Signature ​

get error(): string | undefined

Error message from command execution.

Returns ​

string | undefined

Error message from command execution if it failed.

Implementation of ​

CommandResult.error

exitCode ​

Get Signature ​

get exitCode(): number

Command execution exit code. 0 if the command finished successfully.

Returns ​

number

Command execution exit code. 0 if the command finished successfully.

Implementation of ​

CommandResult.exitCode

stderr ​

Get Signature ​

get stderr(): string

Command execution stderr output.

Returns ​

string

Command stderr output.

Implementation of ​

CommandResult.stderr

stdout ​

Get Signature ​

get stdout(): string

Command execution stdout output.

Returns ​

string

Command stdout output.

Implementation of ​

CommandResult.stdout

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.

js
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:

js
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();
