Ray distributed debugger failed when accepting connection

1

I’m using ray debugger on vscode, I followed the official instructions to set breakpoint and run my code, the code stops at the breakpoint, then I use the ray distributed debugger to connect to that port by adding one cluster 127.0.0.1:46898, the following error happened:

(main_task pid=77949) RemotePdb session open at localhost:34269, use 'ray debug' to connect...
(main_task pid=77949) RemotePdb accepted connection from ('127.0.0.1', 46898).
