Running:
```
harness-application clockdate -t flask-server
```
with latest [develop](https://github.com/MetaCell/cloud-harness/commit/27ae0fe447ba16b9f31a43269cfb3d5076ab16ff)

returns:
```

Expected:
- Generate the application stubs

Start at tools/harness-application line 73 and trace the flask-server path to the generate_server call shown in the traceback. Run harness-application clockdate -t flask-server after the change and verify that the application stubs are generated without the missing-argument error.
