I use VScode and ruby version 2.6.3.

{
"name": "Attach to Docker",
"type": "Ruby",
"request": "attach",
"remotePort": "9000",
"remoteHost": "0.0.0.0",
"remoteWorkspaceRoot": "/data",
"cwd": "${workspaceRoot}",
"showDebuggerOutput": true
}

I had to remove/deactivate all the breakpoints to avoid this error. However, with removed/deactivated breakpoints, the debugger cannot be attached to the running code, which goes as soon as I click the debug button.
