On which version does the cloud debugger takes snapshot.
Is it from default version?
if yes, how can I make it takes snapshot of some other version.
this page doesn't talks about versions.
回答1:
Right -- Currently the debugger only works on the default version of the app engine app. You need to have the source code for that version of your app in the default branch of the git repo.
回答2:
If you have multiple versions (or modules) of the app deployed at the same time, the debugger UI (Google Developer Console --> Source Code --> Debug) will should a drop down. You can then choose the version and the module you want to debug.
