Python Hello, World! not working, 'Terminal can not connect', breakpoints are not hit.

Describe the bug

I am a new user. Started a python workspace with the Hello, World! workspace.

I am using https://che.openshift.io/ and was directed here to file a bug report.

I set a breakpoint in the two lines of the program, and load the Python debugging configuration. When I start debugging, the breakpoints are not hit. The _ run window shows “Hello, World!” each time I try: execution completes.

Workspace definition: metadata: name: wksp-7k5f projects:

• name: python-hello-world source: location: ‘https://github.com/che-samples/python-hello-world.git’ type: git branch: master attributes: persistVolumes: ‘false’ components:
• id: ms-python/python/latest memoryLimit: 512Mi type: chePlugin
• mountSources: true memoryLimit: 512Mi type: dockerimage alias: python image: ‘quay.io/eclipse/che-python-3.7:nightly’ apiVersion: 1.0.0 commands:
• name: run actions:
  • workdir: ‘${CHE_PROJECTS_ROOT}/python-hello-world’ type: exec command: python hello-world.py component: python

When I attempt to execute the script in the debugger, I get a pop error "Terminal failed to connect. " Contents of the output window:

… leaving me confused. It’s ‘hello world’, it should just work 😃

@timrichardson Make sure you use internalConsole in a debug configuration. Supporting of integrationTerminal hasn’t been deployed yet.
