Debugging No Longer Works for DX CLI

Question

Lately in VS Code, my custom DX CLI plugin is no longer stopping when using the --dev-suspend flag, and the commands just run like normal. Breakpoints are no longer being hit when using the flag.

Output of node --version: v12.21.0

Output of code --version: 1.56.2 054a9295330880ed74ceaedda236253b4f39a335 x64

Output of sfdx --version: sfdx-cli/7.110.0 win32-x64 node-v14.17.3

Here is what my launch.json file configuration looks like:

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.

and my tasks.json:

          "message": 6
        }
      }
    }
  ]
}

In my settings.json in VS Code, I have tried toggling "debug.javascript.usePreview": back and forth between true and false but that doesn't seem to make any difference.

Has anyone run across similar issues with the CLI?

Answer 1

Looks like the issue was the AutoAttach feature under File > Preferences > Settings > Extensions > JavaScript Debugger > Auto Attach Filter. Setting it to smart didn't seem to work, but once set to always everything worked again.
