When the server runs locally, it is unable to POST to /events

[neutralino1]

When the server runs locally (either via $ bazel run ... or $ sematic start) and the SocketIO server is the same as the API server, the server is unable to POST to /events (POST to itself) to trigger SocketIO broadcasts.

This error blocks in the pipeline logs (not server logs):

ERROR:engineio.client:packet queue is empty, aborting

This hasn't been too much of an issue yet, because when running pipelines with LocalResolver, most requests to POST /events are made by the resolver, not by the server. When using CloudResolver, some of them are made by the server, but then it is assumed that the server is deployed via the Helm chart, which deploys a separate SocketIO server.
