Has anyone had trouble with differences in how WebSocket clients work when running locally with `wrangler dev --local `vs plain

wrangler dev

or when deployed? I am building a WebSocket client for Discord's Gateway API using DOs. Everything works when running locally with

--local

, but when I remove

--local

or when I deploy to CF, my WebSocket client (created via

new WebSocket()

) immediately gets an error event that says

Failed to establish the WebSocket connection: expected server to reply with HTTP status code 101 (switching protocols), but received 401 instead.

. Discord's Gateway WS protocol doesn't require any authorization to open the WS connection normally (a token gets passed in a message later), and this exact same code works with

wrangler dev --local

. Could there be some difference in how

new WebSocket()

when deployed to Cloudflare vs when running locally?
