[Bug]: Executor error: cannot access local variable 'http_requests' where it is not associated with a value

[RWL-Dittrich]

Steps to Reproduce

1. Try to launch GPT-oss 120b in a cluster of two mac mini's (I haven't tested other big models, small non-spread models seem fine)
2. After the model finishes loading an error occurs

Expected Behavior

I expect the cluster to run like it used to on previous versions

Actual Behavior

An error occurs when the cluster finishes loading on the second node that joins the cluster
