[bioontology-support] Classes Subtree Search endpoint

Dear NCBO Support Team,

I am facing some difficulties using the new API. I am writing a script which
should lookup if words of a given sentence occur in a number of ontologies
and if they do, extract the id, prefLabel, synonyms the word found and the
position in the sentence.

So what I did is following: 

First I use the Annotator endpoint to identify word occurences of a given
ontology, e.g. SNOMEDCT:

Then I extracted the found <text> (here “text”), the class <id> (here
“”), and the
ontology acronym (here “SNOMEDCT”).
With those parameters I invoke the Classes Subtree Search endpoint to get
<prefLabel> and the <synonyms>:

This works like a charm with the SNOMEDCT ontology. However with other ones,
e.g. FMA it fails.
Gives me a 502 Bad Gateway.

Could you please comment on this? Am I missing sth?
