Firstly, read the official document this answers all question you would have about setting the right attributes for different scenarios using launch.json.

Now, to specifically answer this question, the ${workspaceFolder} is basically containing directory of the .vscode directory, which is your project root directory. So, when setting specific files as your debugging program, remember to map the path from the project root directory, or in other words the relative path of the file that is to be set as the debugging program. This can be easily obtained from the IDE (VS Code) by simply right-clicking the file and selecting the Copy Relative Path option. Then proceed to paste this next to the ${workspaceFolder} in the program attribute in your launch.json file, like below, will fix the problem.

"program": "${workspaceFolder}/"

Replace relative path with your copied relative path as mentioned before Note that I am on a Mac platform. Please use platform appropriate path separators

Alternatively, not specifically using a launch configuration makes sense if it's a not-for-production or a simple app that does not warrant a launch config file. However, if not, it is super useful when debugging in a Multi-target environment (server, client). In my opinion, using a compound launch configuration setup makes things a lot easier. Read this section of the official docs to learn how to set it up keeping in mind the relative paths of your server and client files.
