What is the bug?
At the moment, when error occurs here (example: when chat agent is not able to access memory service), the response sent to the user is:

data: {"error": "[ip-10-0-105-16.us-west-2.compute.internal][10.0.105.16:9300][cluster:admin/opensearch/ml/execute/stream]"}

Which is not very helpful. We should show a proper error explaining what went wrong instead.
