Library Tactician Code Bugs

I think I did everything correctly, but for some reason keeps coming up with an error, but the issue is with the code that was already given. Can someone please help?

Code:

# Soldiers spread out in a circle and defend.
def commandSoldier(soldier, soldierIndex, numSoldiers):
    angle = Math.PI * 2 * soldierIndex / numSoldiers
    defendPos = {"x": 41, "y": 40}
    defendPos.x += 10 * Math.cos(angle)
    defendPos.y += 10 * Math.sin(angle)
    hero.command(soldier, "defend", defendPos);

# Find the strongest target (most health)
# This function returns something! When you call the function, you will get some value back.
def findStrongestTarget():
    mostHealth = 0
    bestTarget = None
    enemies = hero.findEnemies()
    # Figure out which enemy has the most health, and set bestTarget to be that enemy.
    max = 0
    for enemy in enemies:
        if enemy.health > max:
            max = enemy.health
    
    # Only focus archers' fire if there is a big ogre.
    if bestTarget and bestTarget.health > 15:
        return bestTarget
    else:
        return None


# If the strongestTarget has more than 15 health, attack that target. Otherwise, attack the nearest target.
def commandArcher(archer):
    nearest = archer.findNearestEnemy()
    if archerTarget:
        hero.command(archer, "attack", archerTarget)
    elif nearest:
        hero.command(archer, "attack", nearest)

archerTarget = None

while True:
    # If archerTarget is defeated or doesn't exist, find a new one.
    if not archerTarget or archerTarget.health <= 0:
        # Set archerTarget to be the target that is returned by findStrongestTarget()
        archerTarget = findStrongestTarget()
    
    friends = hero.findFriends()
    soldiers = hero.findByType("soldier")
    # Create a variable containing your archers.
    archers = hero.findByType("archer")
    for i in range(len(archers)):
        archer = archers[i]
        commandArcher(archer, i, len(archers));
    for i in range(len(soldiers)):
        soldier = soldiers[i]
        commandSoldier(soldier, i, len(soldiers));
    # use commandArcher() to command your archers
    commandArcher()

Issue:

@Numb_Little_Bug
what line is it on?

also, define archerTarget by using function findStrongestTarget() in function commandArcher.
and your for-loops are overcomplicated.
try these:

for archer in archers:

for soldier in soldiers:

then you will not have to define soldier
your commandArcher input is too complicated
just do commandArcher(archer)
