FatalError

When a FatalError is thrown in a step, the step fails without retrying and the error bubbles back to the workflow logic.

Use FatalError when a failure is intentional or unrecoverable and retrying would be wasteful or harmful.

import { FatalError } from "workflow"

async function fallibleWorkflow() {
    "use workflow"
    await fallibleStep();
}

async function fallibleStep() {
    "use step"
    throw new FatalError("Fallible!") 
}
