AFFECTSComponent

CAUSED_BYProblem

Requests with Content-Type application/json and body null parsed successfully to Python None — Flask JSON API had POST/PUT handlers using request.json and immediately calling data.get(...). Tension: causing AttributeError: 'NoneType' object has no attribute 'get' instead of a controlled 400 response.

CAUSED_BYProblem

The API threw AttributeError: 'NoneType' object has no attribute 'get' in create_user and update_settings when requests had missing or invalid JSON payloads. The code assumed request.json was a dict and called .get() on it.
