Describe the Bug

Wrangler won't respect the no_proxy environment variable.

My proxy could not handle the requests send by wrangler dev. When I try to close the dev server (pressing x in the terminal), a Failed to unregister worker error pop out. See the logs for more details.

I've configured my no_proxy to localhost,127.0.0.1, but wrangler still sends the request through proxy. I'm not sure if this is intended or a bug.

Please provide any relevant error logs
