d27610f138
This simple patch adds support for storing the HTTP error description that Vector Store client receives from vector store. Until now it was just printed to the log but it was not returned. For this reason it was not forwarded to the drivers which forced users to access ScyllaDB server logs to understand what is wrong with Vector Store. This patch also updates formatter to print the message next to the error code. Fixes: VECTOR-189
