Mapping Key Error when all word results below the min_score

[KennyWu]

I noticed an issue when experimenting with the map_terms() functions. When I attempt to map a single term, and the results do not have any words that are above the min score, I get a key error message. Here is my input:

dfl = text2term.map_terms(source_terms=["dengue virus infection"], max_mappings=3, min_score = 0.9,
                          `target_ontology="ncit")

And my error output:

KeyError Traceback (most recent call last)
