Rebuild a page from the hub's sources

Rebuilds a generated page from the hub's cached sources — the crawled website text and the notes it was written from — discarding any manual edits, and re-indexes it. The work finishes before the response: the content you get back is already the regenerated page and its origin is reset to generated, so there is nothing to poll. Pages you authored have no sources and answer 409 KNOWLEDGE_PAGE_NOT_REGENERABLE; so does a generated page whose sources have since been removed. The hub's owner can regenerate, and so can anyone on the team when it is the team's shared hub, at most 10 times per minute and 200 per day on top of the shared rate bucket.

Errors:

• 404 KNOWLEDGE_HUB_NOT_FOUND — No hub with that id, it was deleted, or it belongs to another team.
• 404 KNOWLEDGE_PAGE_NOT_FOUND — No page with that id on this hub.
• 409 KNOWLEDGE_PAGE_NOT_REGENERABLE — The page has no cached sources to rebuild from (you authored it, or its sources were removed).
• 409 KNOWLEDGE_HUB_NOT_READY — The hub is still building, or its build never finished.
• 409 KNOWLEDGE_HUB_PAGES_UNAVAILABLE — The hub predates knowledge pages.
• 403 KNOWLEDGE_HUB_OWNER_ONLY — You can read this teammate's hub, but it is not your team's shared hub, so only its owner can regenerate pages.
• 422 VALIDATION_FAILED — hubId or pageId is not a 24-character hex id.
• 500 UNEXPECTED_ERROR — The synthesis model failed, or the regenerated page could not be re-indexed — retry.
• 429 RATE_LIMITED — The shared campaigns bucket was exceeded, or more than 10 regenerations in a minute / 200 in a day.
