How can I resolve this?

[ACE07-Sev]

This issue can be resolved by adding a AtomicType.PREPOSITIONAL_PHRASE to the IQP ansatz. for versions under 0.2.3 it will be AtomicType.PREPOSITION, and for 0.2.3 AtomicType.PREPOSITIONAL_PHRASE.

[y-richie-y]

Thanks for the issue! Yes, it is necessary in general to provide mappings for noun, sentence and propositional phrase types in the Ansatz mapping. We will update the examples in the documentation to reflect this.
