Hi, I'm trying to get the Pathway Common API to return all interactions between a set of genes. I came across some situations where the API returns an empty string, but the website shows an interactions. Specifically, calling for all paths of length 1 between ID2 and TCF4:

Does anyone know what is going on? Is the API querying an old version of the database? Are my queries incorrect?
