getException

Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

Since this is a failed result wrapper, this always returns the exception thrown during the Awaitable operation

public function getException(): Te;

getException() is the same as `getResult() in this case.

Returns​

  • Te - The exception thrown during the Awaitable operation.
