Bug: The code catches a private gRPC exception, _InactiveRpcError, and incorrectly maps all resulting errors to an HTTP 404 status, which can mask the underlying issue.
_{Severity: MEDIUM}

Suggested Fix

Refactor the exception handling to catch the public grpc.RpcError exception. Inspect the error's status code using the .code() method to return an appropriate HTTP status. For example, map grpc.StatusCode.UNAVAILABLE to HTTP 503 (Service Unavailable).

Potential issue: The exception handling for gRPC calls is fragile because it catches
`_InactiveRpcError`, a private implementation detail of the `grpc` library that could
change without notice. Furthermore, it incorrectly maps all such RPC errors to an HTTP
404 (Not Found) response. This is semantically incorrect for service availability issues
(like `UNAVAILABLE` or `DEADLINE_EXCEEDED`), which should return a 5xx error. This
misrepresentation can mislead clients and complicate debugging of infrastructure
problems.
