Love2D 错误：'rectangle'的第二个参数错误（期望数字，得到nil）

我不知道我做错了什么……我在player.draw()函数中出现了错误。它所说的错误参数在love.graphics.rectangle()方法中。它说v.x是错误的参数。但它应该可以工作的。因为它访问了表或数组中元素的字段，对吗？有人能告诉我我做错了什么以及如何修复吗？非常感谢您！这是我的代码：

require "scripts.player"

width = love.graphics.getWidth()

block = {}
block.width = 60
block.height = 10
block.speed = 150
block.timer = 0
block.timerLim = math.random(1,2)
block.spawnX = math.random(0, width - player.width)

function block.spawn(x,y)
    table.insert(block, {x = x, y = y})
end

function block.move(dt)
    for i,v in ipairs(block) do
        v.y = v.y + block.speed * dt
    end
end

function block.draw()
    for i,v in ipairs(block) do
        love.graphics.setColor(255,0,255)
        love.graphics.rectangle("fill", v.x, v.y, block.width block.height)
    end
end

function block.spawnHandler(dt)
    block.timer = block.timer + dt
    if block.timer > block.timerLim then
        block.spawn(spawnX, -10)
        block.timer = 0
        block.timerLim = math.random(1,2)
        block.spawnX = math.random(0, width - block.width)
    end
end

-- 父级函数 --

function DRAW_BLOCK()
    block.draw()
end

function UPDATE_BLOCK(dt)
    block.move(dt)
    block.spawnHandler(dt)
end
