VSCode debugger extension doesn't work on theia

[Nina0408]

Bug Description:

Hi There,

I have implemented a debugger on VSCode and want to test it on theia, but I got the error says: There was an error starting the debug session, check the logs for more details. I checked the output view, there is no any error information showed.

I also download a vsix file of mock debug in https://marketplace.visualstudio.com/items?itemName=andreweinand.mock-debug and try it on theia, when click debug, there is no error displayed but either no any response.

and then I found an existing issue closed to my regarding debugger #6490. which says about adding launch.json file before debugging, and then I got below error after adding launch.json, btw, my debugger is inline mode:

root ERROR Error starting the debug session TypeError: r.DebugAdapterInlineImplementation is not a constructor
