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} [`SlackWebhookError`](https://docs.slack.dev/tools/node-slack-sdk/reference/webhook/classes/slackwebhookerror.md).[`stackTraceLimit`](https://docs.slack.dev/tools/node-slack-sdk/reference/webhook/classes/slackwebhookerror.md#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` #### Inherited from {#inherited-from-5} [`SlackWebhookError`](https://docs.slack.dev/tools/node-slack-sdk/reference/webhook/classes/slackwebhookerror.md).[`captureStackTrace`](https://docs.slack.dev/tools/node-slack-sdk/reference/webhook/classes/slackwebhookerror.md#capturestacktrace) * * * ### prepareStackTrace() {#preparestacktrace} ``` static prepareStackTrace(err, stackTraces): any; ``` Defined in: packages/webhook/node\_modules/@types/node/globals.d.ts:55 #### Parameters {#parameters-2} ##### err {#err} `Error` ##### stackTraces {#stacktraces} `CallSite`\[\] #### Returns {#returns-2} `any` #### See {#see} [https://v8.dev/docs/stack-trace-api#customizing-stack-traces](https://v8.dev/docs/stack-trace-api#customizing-stack-traces) #### Inherited from {#inherited-from-6} [`SlackWebhookError`](https://docs.slack.dev/tools/node-slack-sdk/reference/webhook/classes/slackwebhookerror.md).[`prepareStackTrace`](https://docs.slack.dev/tools/node-slack-sdk/reference/webhook/classes/slackwebhookerror.md#preparestacktrace)
