[SOLVED] Error setting breakpoint in Visual Studio Code C++ Debugger

Error setting breakpoint in Visual Studio Code C++ Debugger

Until last week I was able to hit breakpoints in my C++ code in VSCode. Since last two days when I try to attach the debugger to the remote process, the breakpoints grey out.

On bringing my mouse pointer on a greyed out breakpoint, the message says:

Error setting breakpoint. The debug engine threw an exception.

, as shown in the image below:

My launch.json looks like the following:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "prgAttach",
            "type": "cppdbg",
            "request": "attach",
            "program": "~/JBL/SC-253/bin/azg",
            "processId": "${command:pickProcess}",
            "MIMode": "lldb"
        },
        //Followed by other debug configurations...
    ]
}

My platform info, obtained from Code > About Visual Studio Code, is:

Version: 1.41.1

Anyone else familiar with the problem? Any suggestions/workarounds?

I have:

tried uninstalling the C/C++ extensions and reinstalled them. No effect.
verified that I'm attaching to the correct process.
restarted the process too, to do a fresh attach.

Solution

I have a feeling that your issue could be related to this (you don't provide your full platform information): https://github.com/microsoft/vscode-cpptools/issues/3829

LLDB itself still works, it's just broken from within VS Code, but a fix is in the works according to the link.

It could also be worth re-generating launch.json and trying that out.
