### Description Im ingesting data using LangChain WeaviateVectorStore.from\_documents() function. After successfully inserted ~600K of objects (embedding length 1536), I start getting the following error `weaviate.exceptions.UnexpectedStatusCodeError: Collection may not exist.! Unexpected status code: 503, with response body: None.` I tried to enable async indexing, and sent a Cluster Scale request. But the error still happens. * * * ### Server Setup Information - Weaviate Server Version: 1.25.7 - Deployment Method: Weaviate cloud - Multi Node?
