Constructors

Properties

command: Record<string, any>

The original command that was sent to the API, as a plain object. This is the raw command, not necessarily in the exact format the client may use, in some rare cases.

Example

{
insertOne: {
document: { _id: 'doc10', name: 'Document 10' },
},
}
message: string

A human-readable message describing the first error.

This is always equal to errorDescriptors[0]?.message if it exists, otherwise it's given a generic default message.

name: string
rawResponse: RawDataAPIResponse & {
    errors: ReadonlyNonEmpty<DataAPIErrorDescriptor>;
}

The raw response from the API

Type declaration

Example

{
status: {
insertedIds: [ 'id1', 'id2', 'id3']
},
errors: [
{
family: 'REQUEST',
scope: 'DOCUMENT',
errorCode: 'DOCUMENT_ALREADY_EXISTS',
id: 'e4be94b6-e8b5-4652-961b-5c9fe12d2f1a',
title: 'Document already exists with the given _id',
message: 'Document already exists with the given _id',
},
]
}
stack?: string
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

  • get warnings(): readonly DataAPIWarningDescriptor[]
  • A list of error descriptors representing the individual errors returned by the API.

    This will likely be a singleton list in many cases, such as for insertOne or deleteOne commands, but may be longer for bulk operations like insertMany which may have multiple insertion errors.

    Returns readonly DataAPIWarningDescriptor[]

Methods

  • 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

    • targetObject: object
    • Optional constructorOpt: Function

    Returns void
