In the log I see:

[   221.310][WARN] Empty lines array found for constellation "CON chinese 063" ("天庙")
[   221.311][WARN] Empty lines array found for constellation "CON chinese 092" ("军门")
[   221.323][WARN] Empty lines array found for constellation "CON chinese 150" ("东瓯")
[   221.323][WARN] Empty lines array found for constellation "CON chinese 166" ("器府")
[   221.323][WARN] Empty lines array found for constellation "CON chinese 170" ("天稷")
[   221.336][WARN] Empty lines array found for constellation "CON chinese 264" ("土司空(奎宿)")

Of course these constellations has no stars data for lines. These xingguans was officially deleted in 1752 and I guess we should remove these lines from index.json file.

    The six redundant constellations can indeed be deleted. At that time, when there was only this one Chinese Sky Culture, the names of these six constellations were kept merely for the convenience of possible future processing or historical comparison. (Popular science books introducing Chinese Sky Culture usually mention that these six constellations once existed. Now that there are sky cultures from different historical periods, the names of these six constellations indeed no longer need to be retained.
