To add it to your workflow:

• Type Leonardo
• Click Self-Host Hub (Leonardo)

Self-Host Hub (Leonardo) v0.5.0 — new async/webhook response mode

Just shipped an update to the n8n-nodes-selfhosthub Leonardo node that fixes a pain point a lot of you have hit: Leonardo image generations that take minutes and time-out while the node sits there polling.

What’s new — a “Response Mode” dropdown:

• Wait for Image (Poll) - the original behavior: submit, poll, return the finished image. Still the default, so nothing changes for existing workflows.
• Submit Only (Async / Webhook) - submits the generation and returns the generationId immediately, no waiting, no timeout. You then catch the finished image with an n8n
  Webhook trigger node.

How async mode works: Leonardo delivers completed images to the webhook callback URL configured on your Production API key (set in the Leonardo dashboard — it’s
account-level, not per request). Point that at an n8n Webhook node, match the incoming image_generation.complete payload to the generationId the node emits, and continue
the workflow. No more 15-minute hangs or failed executions.

Get it / upgrade: Settings → Community Nodes → n8n-nodes-selfhosthub (or hit Update if you already have it). Fully backward compatible.
