Traceback (most recent call last):
  File "app.py", line 6, in <module>
    app.init_routes(prefix_routes=True)
  File "/home/daniel/Projects/Personal/pyterrier/pyterrier/pyterrier.py", line 115, in init_routes
    self._route_discovery.register_actions(prefix_routes)
  File "/home/daniel/Projects/Personal/pyterrier/pyterrier/core/route_discovery.py", line 62, in register_actions
    actions = self._prefix_routes(controller, actions)

    for route, verb, func in actions:
ValueError: too many values to unpack (expected 3)
