How to fail workflow from the activity?

[arrowcircle]

Hey! I am looking for a way to fail workflow from the activity.
I found termiation example, but this sets workflow status to terminated, not to failed.

Is there are any way to fail workflow from the activity?

Not sure if you were looking for an API to fail a workflow, I'm not sure if there is one really, but if you raise a custom error and you add it to the non_retriable_errors collection of the retry_policy config, that should work.

@santiagodoldan Thanks for the suggestions. In this case, it will show workflow as terminated (grey), not failed (red). This breaks visibility in UX a lot.

I don't think this is true. Raising a non-retriable error will fail the activity and the workflow correctly (failed, not terminated). We have been using this successfully in our app.
