OptionalstackReadonlystageStaticstackThe 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.
Safe JSON projection. Raw messages, stacks, details, bodies, and causes are intentionally omitted.
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 for runtime-level binding failures. Per-source / per-request protocol failures keep their existing error classes (
HonuaCapabilityNotSupportedError,HonuaHttpError) and surface on the per-Sourcepromises fromruntime.datasetand through the sharedHonuaClientinterceptor chain. Thesource-errorevent onHonuaRuntimeEventis the canonical observable for per-source failures: the loader emits it for tolerant bind-time failures (sourceErrorPolicy: "tolerant", the default) andHonuaMapRuntime.reportSourceErroremits the same event for query-time rejections forwarded by mixed-source consumers — seedocs/composition.md.
