StaticstackThe 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.
ReadonlycodeHuman-readable error code.
ReadonlystatusThe HTTP status code.
ReadonlystatusThe HTTP status text.
ReadonlyurlThe URL of the failed request.
ReadonlyheadersThe normalized response headers.
ReadonlybodyThe response body, or null if not read.
OptionalcauseOptionalstackReturns true if the status code is a client error (4xx).
Returns true if the status code is a server error (5xx).
Returns true if the status is 404 Not Found.
Returns true if the status is 401 Unauthorized.
Returns true if the status is 403 Forbidden.
Returns true if the status is 429 Too Many Requests.
Returns true if the status is 410 Gone.
Returns true if the status is 409 Conflict.
StaticcaptureCreates 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();

Thrown when a response has an HTTP error status (4xx/5xx).
