ReadonlybodyOptionalcauseReadonlycodeReadonlycredentialsWhether the failed request carried credentials: true if it did, false for
an endpoint that accepts them but was called without (e.g. a guest find),
undefined for an endpoint that takes none (whoami). Lets the CLI give the
right hint — or none — for an auth error.
ReadonlydetailReadonlyhttpReadonlyloginTrue when helloworld/logincheck answered that the credentials were not accepted
— live, an HTTP 200 whose Status is an error text. Such an answer carries no code and no error status, so this flag is
what makes it an auth error (isAuthError).
ReadonlymethodOptionalstackReadonlystatusReadonlyurlStaticstackThe 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.
True when the API rejected the credentials: the GENESIS logical code 15
("Sie sind nicht berechtigt ..." — no/unrecognized credentials), code 2 in a
flat status or on a non-2xx reply (wrong username/password or token — the live
server's HTTP 404 + { Code: 2 }, and the same flat body on an HTTP 200; the
engine sets httpStatus for both), a transport-level 401/403, or a rejected
logincheck (loginRejected, live an HTTP 200 with an error text). The CLI
appends a credentials hint for these.
True when the API signalled "no such object": the GENESIS logical code 90
(requested object not found), or a transport-level HTTP 404 that did NOT
carry a contradicting GENESIS code in its body — the live server answers
wrong credentials with HTTP 404 + { Code: 2, ... }, which is an auth
problem, not a missing object. Also code 104 ("keine Objekte"), which the
engine raises only for a file download (postRaw) — on the JSON endpoints
104 is a valid empty result and never thrown. Lets the CLI map a genuine
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 — while authentication failures arrive as a bare{ Code, Content, Type }object at the top level, on a non-2xx status (verified live: HTTP 401 with Code 15 for missing credentials, HTTP 404 with Code 2 for wrong credentials — see engine.ts). This error therefore models both worlds, together when needed:httpStatusis set for transport/HTTP failures (non-2xx, e.g. a gateway 502 or an auth-layer 401), and for a flat{ Code, Content, Type }status on any reply, a 200 included (the auth-failure shape);codeis set for a GENESIS logical error, taken fromStatus.Codeor the flat top-levelCode(e.g. 90 = object not found, 98 = table too large, 15 = not authorized, 2 = wrong credentials), withstatusTypetheType("Fehler"/"ERROR").At least one of the two is always present, and both are when a non-2xx reply carried a GENESIS status body or a 2xx reply a flat one;
