Recursion Error during injection

I'm getting a recursion error when an object is instantiated using an overridden container with this rough form. Any thoughts on what the cause might be?

I'm new to dependency injection so I hope the structure is correct. I have a window that displays a transformed image, and I want the mouse to behave differently depending on the type of transform.

class ControlPointAction(enum.Flag):
    """Possible interactions for control point(s)"""
    NONE = 0
    CREATE = 1
    DELETE = 2
    TRANSLATE = 4

class TransformType(enum.Enum): 
    RIGID = 'Rigid'
    GRID = 'Grid'
    MESH = 'Mesh'
    RBF = 'RBF'


ControlPointActionCommandMapType = Dict[ControlPointAction, Factory[ICommand]]

class Container(containers.DeclarativeContainer):
# We want a different set of transform commands for each type of transform
    action_command_map = providers.Dependency(
        instance_of=providers.Dict[TransformType, ControlPointActionCommandMapType])

@containers.override(Container)
class StosContainer(containers.DeclarativeContainer):
    action_command_map = providers.Dict[TransformType, ControlPointActionCommandMapType]({
        TransformType.GRID: providers.Dict({
            ControlPointAction.NONE: providers.Factory(DefaultTransformCommand),
            ControlPointAction.TRANSLATE: providers.Factory(TranslateControlPointCommand),
        }),
        TransformType.MESH: providers.Dict({
            ControlPointAction.NONE: providers.Factory(DefaultTransformCommand),
            ControlPointAction.TRANSLATE: providers.Factory(TranslateControlPointCommand),
        }),
        TransformType.RBF: providers.Dict({
            ControlPointAction.NONE: providers.Factory(DefaultTransformCommand),
            ControlPointAction.TRANSLATE: providers.Factory(TranslateControlPointCommand),
        }),
        TransformType.RIGID: providers.Dict({
            ControlPointAction.NONE: providers.Factory(DefaultTransformCommand),
            ControlPointAction.TRANSLATE: providers.Factory(TranslateControlPointCommand),
        })
    })


class Command:
   @inject
   def __init__(transform_type_to_command_action_map: Dict[TransformType, ControlPointActionCommandMapType] = Provide[Container.action_command_map]):
   """Infinite recursion occurs when constructor is invoked"""
        pass
