ReadonlyreasonOptionalstackStaticstackThe 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.
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();

Raised when Graph.hydrate receives a snapshot that does not match the live graph's capabilities — either an unsupported
schemaversion or aschemaHashthat diverges from the digest of the currently registered node id-set.Remarks
Catches the hydration-mismatch race where the server-snapshot id-set diverges from the client node-set. The check is structural:
schemaHashis the persistence-side mirror of Graph.subscribe's narrow-capability discipline, ensuring a stale or malicious snapshot whose id-set diverges from the live graph is rejected up-front rather than silently tearing engine state. The capability check is structural, not a hope.Param: reason
Discriminator:
'schema-version'rejects an unsupported wire-format version;'schema-hash'rejects a capability-mismatch on a supported version.Param: detail
