+title: CancelledError

+
+Defined in: [packages/query-core/src/retryer.ts:77](https://github.com/TanStack/query/blob/main/packages/query-core/src/retryer.ts#L77)
+
+The error thrown by a `Retryer` (and surfaced to `query.promise`/`mutation`) when a fetch is cancelled, e.g. via
+`query.cancel()`. `revert`, if `true`, tells the caller to restore the state the query was in before the fetch
+started instead of surfacing the error. `silent`, if `true`, tells the caller to suppress this error and instead
+resolve with the promise of the fetch that triggered the cancellation.
+
+## Example
+
+```ts
+query.cancel()
+
+try {
+  await query.promise
+} catch (error) {
+  if (error instanceof CancelledError) {
+    // the fetch was cancelled, e.g. via `query.cancel()`
+  }
+}
+```

+
+The `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.
+
+#### Inherited from
+
+```ts
+Error.stackTraceLimit
+```
+
+## Methods
+
+### captureStackTrace()
+
+```ts
+static captureStackTrace(targetObject, constructorOpt?): void;
+```
+
+Defined in: node\_modules/.pnpm/@types+node@22.19.15/node\_modules/@types/node/globals.d.ts:52
+
+Creates a `.stack` property on `targetObject`, which when accessed returns
+a string representing the location in the code at which
+`Error.captureStackTrace()` was called.
+
+```js
+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:
+
+```js
+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();
+```
+
+#### Parameters
+
+##### targetObject
+
+`object`
+
+##### constructorOpt?
+
+`Function`
+
+#### Returns
