Hi @wuwei88
You you can enable the Target console logging through Adobe Experience platform debugger extension. I just tried and it's working correctly.
Here are the steps.
1) Open your web page in browser and then enable the Adobe Experience platform debugger extension.
2) Sign-in in the extension itself and once sign in completely reload the page.
3) If you're using Experience Platform Tags ( Adobe launch / data collection ) then inject the right environment embed code
4) Enable console logging and Save.

5) Please reload the web page and ensure the injected embed code take into effect.
6) in Target configuration, enable the Target console Logging.

7) once done, you can able to see the logs in console. Here are the screenshot.

Hope this helps.
Thank you.
