I’m using python 3.8 as my runtime rather than Node.js; when I run the Debug SST Start debug configuration, the app runs, but breakpoints are not triggered.

Is debugging of Python-based SST apps in Visual Studio Code currently supported?

Oh that debug config might be specifically for Node. You might’ve to play around with it.

Thanks, @jayair . I tried changing the type parameter in the Debug SST Start configuration to “python”, but when I press F5, I get the following:

Invalid message: either “program”, “module”, or “code” must be specified

If anyone has successfully configured their launch.json so that they can successfully debug SST apps that use a Python runtime, please share your launch.json configuration.

Obviously, this debugging setup doesn’t work anymore for Ion.

The launch.json config needs to change from

"runtimeArgs": ["start", "--increase-timeout"],

to

"runtimeArgs": ["dev"],

to start.

Haven’t figured out how to increase the timeout so far.

Also there is following warning:

Warning: You are using a global installation of SST but you also have a local installation specified in your package.json. The local installation will be used but you should typically run it through your package manager.

I also created an issue for it.
