# Clearing Mocked data no longer breaks a webhook Flow

> <p>The Pull from webhook step shows <code>{}</code> in its Mocked data field when nothing is set, but deleting the contents saved an empty value instead. The next webhook run failed with a calculation error and zero rows. An empty field reads as <code>{}</code> again, and steps already saved that way repair themselves on their next run. Mocked data that isn&rsquo;t valid JSON now tells you so instead of failing generically.</p>
