# didFinishRunningWithError: Sent by the action to itself when it has finished running asynchronously. ``` - (void) didFinishRunningWithError:(NSDictionary *) errorInfo; ``` ## Parameters `errorInfo` If an error occurred during asynchronous running of the action, upon return contains an instance of `NSError` that describes the problem. ## Discussion An action that overrides [`runAsynchronously(withInput:)`](/documentation/Automator/AMAction/runAsynchronously(withInput:)) should invoke `didFinishRunningWithError:` on completion, so that Automator can resume running the workflow that the action is part of. --- Copyright © 2026 Apple Inc.
