Server and client mappings

[Metisav]

If i use config for client debug like:
import pydevd;pydevd.settrace(host="", port=8888, protocol="dap")
mappings in config works correctly i got my local file in VS Code

but if i use server config
import pydevd;pydevd.settrace(host="127.0.0.1", port=8888, protocol="dap")
files opens by path from remote server

maybe i do something wrong

"configurations": [ { "name": "Pydevd", "type": "pydevd", "request": "attach", "port": "8888", "mode": "client", "pathMappings": [ {"localRoot": "/home/artem/Development/triggers/bl-modules/Triggers", "remoteRoot": "/root/services/online-ru/online/modules/Triggers"} ] }, { "name": "Pydevd_server", "type": "pydevd", "request": "attach", "port": "8888", "mode": "server", "pathMappings": [ {"localRoot": "/home/artem/Development/triggers/bl-modules/Triggers", "remoteRoot": "/root/services/online-ru/online/modules/Triggers"} ] }]
