Redux course redux dev tools trace

I am going through the redux course and trying to get the trace option working in dev tools. when I set trace to true I get the following message in the trace section of dev tools. the code compiles, but this error still shows up. thank you for any help.

eval
././src/index.js?:14:48

Module…/src/index.js
http://localhost:9000/app.js:544:1

_webpack_require
http://localhost:9000/app.js:20:30

eval
./multi_(webpack)-dev-server/clilent?:2:18

Hey, I’m having the same problem. Did you find any solution ?

That is not “error” output, it the trace working as expected and saying that line number 14 in index.js dispatched the event. What you are probably looking for is the enriched rendering that prints the actual code near that line in the file.

To get this you need to continue to the next step in the tutorial where Mosh modified the webpack.config.js to add this property:

devtool: 'source-map'

In the videos Mosh already had webpack configured to build source maps so his trace viewer looks more detailed until you continue on to the next step as described above.
