While debugging Unity client websocket closes

[metiscoda]

Following the instructions at the bottom of https://docs.colyseus.io/getting-started/unity-sdk/ I set my pingInterval to 0. When I try to debug a Unity client connected to a colyseus localhost server running my game, I invariably get a closing of the websocket with the callstack below. Anyone have any idea how to make the pingInterval option work?

Websocket closed! Code:1006
