OptionalcauseReadonlyentityThe idempotency entity the store was configured with.
ReadonlynameDiscriminant for consumers that cannot use instanceof across realms.
ReadonlyreasonWhy the backend cannot serve tier C — a fixed vocabulary, so an application can branch on it without matching message text:
'cosmos-unsupported' — a Cosmos DB transaction is one partition, and
the idempotency record cannot be made to share the business partition.'bigtable-unsupported' — Bigtable allows one row per transaction.'mongodb-standalone' — the server refused a transaction (code 20,
IllegalOperation): MongoDB transactions need a replica set.'entity-unavailable' — anything else: the idempotency entity is
missing or unreadable.OptionalstackStaticstackThe 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();

verify()of the storecreateDatabaseIdempotencyStorebuilds when the configured backend cannot serve tier C.The store runs
verify()at startup, before the firstwithin, so an unusable backend is a named startup failure rather than a request that fails every time. The adapter's own error, when there is one, is kept ascausefor the log; the message names the entity and the reason, never a record's contents.Example
