Describe what the problem is?

I run

kupo \
  --ogmios-host $OGMIOS_HOST \
  --ogmios-port $OGMIOS_PORT \
  --since 39916796.e72579ff89dc9ed325b723a33624b596c08141c7bd573ecfff56a1f7229e4d09 \
  --match "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/*" \
  --match "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/*" \
  --match "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY" \
  --match "ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ" \
  --workdir ./kupo/db \
  --prune-utxo \
  --port 1445 \
  --defer-db-indexes

twice. The second time I get

The issue seems to be the duplicated pattern. After removing it, the second time starts fine.

What should be the expected behavior?

Some more useful error message ;)

Ho. Good point. Patterns should probably be compared as a set.
