Problem : The deployed application fails to retrieve data from Weaviate Cloud using gRPC. This issue does not occur locally — it is specific to the production deployment.

Local: Working
Deployed (Cloud): Fails intermittently on retrieval
Root cause
We are currently using the Weaviate Sandbox version, which has performance limitations and may result in gRPC timeouts during cloud-to-cloud communication.

Solution
Migrate from the Sandbox version to a dedicated Weaviate Cloud instance with higher ressources
