Problem with wb_get_topic_latest_works

[fnielsen]

Problem with the topic aspect and perhaps author aspect.

ERROR in app: Exception on /topic/Q189849/latest-works/rss [GET]

During handling of the above exception, another exception occurred:

It seems to time out for me. If it does, I can imagine the returned content is not JSON, causing the simplejson.errors.JSONDecodeError: Expecting value: line 1 column 1 (char 0) ?

Actually, not sure... this is the SPARQL it is running and that works fine: https://w.wiki/BWbk

Running it from the command line works too: python3 -m scholia.rss topic-latest-works Q189849

Actually, works in the browser too. @fnielsen, how can I reproduce the error?
