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. Only the hub's owner can regenerate, 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 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.
