Solution 1:

I found the problem. VS Code doesn't handle symbolic links well. When I set up a project in VS Code in real path debugger started to work properly.

gbajson@misio:~$ realpath /home/gbajson/Sync/clickr/clickr-node-api/clickr-node-api.go
/storage/amoje/Sync/clickr/clickr-node-api/clickr-node-api.go
