    cause?: Error
    code?: string | number

    This is a number in MongoServerError and a string in MongoDriverError

    connectionGeneration?: number
    message: string
    reason?: TopologyDescription

    An optional reason context, such as an error saved during flow of monitoring and selecting servers

    stack?: string
    topologyVersion?: TopologyVersion
    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.

    • get errmsg(): string

      Legacy name for server error responses

      返回 string

    • get errorLabels(): string[]

      返回 string[]

    • get name(): string

      返回 string

    方法

    • 参数

      • label: string

      返回 void

    • Checks the error to see if it has an error label

      参数

      • label: string

        The error label to check for

      返回 boolean

      returns true if the error has the provided error label

    • 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();

      参数

      • targetObject: object
