Breakpoints showing "Unbound breakpoint" in VS Code when debugging React app #2325

Description

I am trying to debug a React application in VS Code, but the breakpoints are not binding correctly.

When I set a breakpoint in my source file, VS Code shows "Unbound breakpoint" and displays the following message:

We couldn't find a corresponding source location, and didn't find any source with the name Api_Call.js.

Project Details:

  • Framework: React
  • Start command: npm start
  • File where breakpoint is set: src/CONNECTION/Api_Call.js
  • OS: Windows
  • Editor: VS Code

Current launch.json configuration:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Launch Chrome",
      "request": "launch",
      "type": "chrome",
      "url": "http://localhost:3000",
      "webRoot": "${workspaceFolder}"
    },        
  ]
}

Issue:
VS Code cannot map the running code in the browser to the local source file, and the breakpoint remains unbound.

Steps to Reproduce:

  1. Start the React application using npm start.
  2. Launch the debugger in VS Code.
  3. Set a breakpoint in Api_Call.js.
  4. Breakpoint appears hollow and shows "Unbound breakpoint".

Expected Behavior:
Breakpoints should bind correctly and pause execution when the code is hit.

Actual Behavior:
Breakpoints remain unbound and the debugger does not stop.
