I have a workspace open in VS Code with multiple nested subdirectories for different projects. When I go to the Debugging Run in the sidebar and click on create a launch.json file a popup prompt appears to Select a workspace folder to create a launch.json file in or add it to the workspace config file with the options in the dropdown being the 1. current open workspace 2. workspace. When I select (1) and add the required configurations to the launch.json file the .vscode/launch.json is located in the root directory of the workspace and NOT the root directory of the project (in this case a React Native project) and when running the debugger I get the following error:

An error occurred while attaching debugger to the application. Seems to be that you are trying to debug from within directory that is not a React Native project root. If so, please, follow these instructions: https://github.com/microsoft/vscode-react-native#customization (error code 604) (error code 1410)

How can I configure the launch.json file for a specific project in a VS Code workspace, rather than for the entire workspace?

  • If I understand correctly, you can create a .vscode folder in each project manually, and add your launch.json there for each project. Perhaps I misunderstand your question though? Commented Nov 22, 2020 at 9:32
  • the issue remains, as in the Debugger menu it does not pick up that you are currently working on a given project in the workspace, so it does not see that workspace_dir/project_dir/.vscode/launch.json file Commented Nov 22, 2020 at 10:14
  • .vscode in a subfolder is not recognized by VSC. Use MultiRoot Workspace Commented Nov 22, 2020 at 10:18

You can work with a MultiRoot Workspace.

  • Open a Workspace with: File | Open Folder
  • Add Workspaces with: File | Add Folder to Workspace
  • Save the MultiRoot Workspace: File | Save Workspace As

Next time you open this MultiRoot Workspace with: File | Open Workspace

Now each Workspace folder can have its own .vscode folder with launch.json and tasks.json.

When you now open a launch.json you can add Configurations by hand or with the Add Configuration... button in the lower right.

In the Debug Bar you can now select a Launch config from any of the Workspaces.

It is also possible to add the different launch configurations for the sub folders of a Workspace, in case you need to launch multiple configs (server and client) but then you need to set the parameters yourself like cwd.

I already have a vs code workspace with multiple projects in it, the issue is opening that workspace and selecting a project at any moment to debug.
@AgentAnon Create .vscode/launch.json and add your configs needed, then select the one you want from the drop down in Debug Bar. Read the doc on VSC Debugging
I did create a .vscode/launch.json file in the root dir of the project, and I cannot select the config whilst the workspace is open, only when I open the project dir itself. Is there a difference between a code-workspace and a MultiRoot Workspace?
If your projects were set up as multi-roots properly then this extension might be of interest: marketplace.visualstudio.com/… You can launch any debug config from any root folder.
code-workspace === MultiRoot Workspace. It depends how many folders you have specified in this code-workspace file, use a different editor to open this json file. It can be 1 or more
