### stackTraceLimit {#stacktracelimit}

```
static stackTraceLimit: number;
```

Defined in: packages/webhook/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.

#### Inherited from {#inherited-from-4}

```
Error.stackTraceLimit
```

## Methods {#methods}

### captureStackTrace() {#capturestacktrace}

```
static captureStackTrace(targetObject, constructorOpt?): void;
```

Defined in: packages/webhook/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 {#parameters-1}

##### targetObject {#targetobject}

`object`

##### constructorOpt? {#constructoropt}

`Function`

#### Returns {#returns-1}

`void`
