It happens because

Doesn't have such type in its map.
Right now I see two possible solutions.
1) When its null fallback to the Object.class type
2) On the side of the component-runtime forbid declare the custom types as the possible after variables types.
We can implement both of them. (1) to support existed connectors (it should be very small amount of connectors, because this feature just was released)
And the (2) - for the future.
I think we can proceed with the (2).
