lazy loading of citation field not possible

[hippke]

I like to find out which papers cite which of my papers. This works fine:

query = ads.SearchQuery(q="author:hippke,m",)
for paper in query:
    print(paper.bibcode, paper.citation_count, paper.citation)

Unfortunately, it costs me n queries from my rate limit where n is the number of my papers.
A solution to use lazy loading was suggested in this issue for exactly my use case. BUT when I add to the ads.SearchQuery:

fl=['bibcode', 'citation_count', 'citation']

I get "None" for the paper.citation instead the list of bibcodes.
Any help appreciated!

OK, I tried again - it seems to work fine now. Might have been related to the server problems. This can be closed
