The reason is the mismatch between catchments and rivers (cachments are level 6 by default and rivers were generated for level 5).

Seems to be fixed. Also, the additional argument needs to be specified for Niger, to limit the number of upstream rivers (currently 5000):
hydroengine in/niger.json --get-rivers=out/rivers-region.geojson --filter-upstream-gt 1000
