“ValueError: max() arg is an empty sequence"

[oneupthedevil]

After trying to run lineups; using

try: lineups = optimizer.optimize(n=num_lineups) except Exception as e: print(f"Error generating lineups: {e}") raise

And trying to #Print lineups using

Print lineups

for lineup in lineups: print(lineup)

I recieve "ValueError: max() arg is an empty sequence"

Cant figure out why? Any help would help
