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.
True when the API signalled "no such object": the GENESIS logical code 90 (requested object not found) or a transport-level HTTP 404. Lets the CLI map a miss to a distinct exit code for scripting.
True for HTTP statuses the engine treats as transient and retries.
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();

The API signalled a failure. GENESIS-Online is unusual: it answers HTTP 200 for most logical errors and carries the real outcome in a
Statusobject in the body (see engine.ts). This error therefore models both worlds:httpStatusis set for genuine transport/HTTP failures (non-2xx, e.g. a gateway 502 or an auth-layer 401);codeis set for a GENESIS logical error, taken fromStatus.Code(e.g. 90 = object not found, 98 = table too large), withstatusTypetheStatus.Type("Fehler"/"Error").At least one of the two is always present;
detailholds the human-readable message (Status.Content, or a parsed field from an HTTP error body).
