React errors indicate the compiled location of the file and not the uncompiled location of the file

Occasionally I have errors and the routing of the error shows into the compiled file and not the uncomplicated file. for example:

react-jsx-dev-runtime.development.js:117 Warning: Each child in a list should have a unique "key" prop.

Check the render method of Container. See https://reactjs.org/link/warning-keys for more information.

at Test
(http://localhost:3000/static/js/bundle.js:4874:5)

instead of

 at Test
    (src/components/Edit.tsx).

Is there any way to config it so i can see the exact problem line & routing?
