Why is this throwing an "Unable to cast value to Object"? [Solved]

This script errors with "Unable to cast value to Object" I am not sure why as I'm pretty sure I'm including the player object. Let me know why.

Errors on Lines 51, 55, and 59 depending on which button you click.

local product1 = 616014127  

local product2 = 616014380

local product3 = 616014575

button1.MouseButton1Down:Connect(function(plr)
	market:PromptProductPurchase(plr,product1)   --These error
end)

button2.MouseButton1Down:Connect(function(plr)
	market:PromptProductPurchase(plr,product2)  --These error
end)

button3.MouseButton1Down:Connect(function(plr)
	market:PromptProductPurchase(plr,product3)  --These error
end)

You're using the first argument given by MouseButton1Down which is the x screen position for the mouse. See the other parameters here.

Since this is done locally you have access to the LocalPlayer from the Players service.

--Example usage for one product id.

local Players = game:GetService("Players")
local market = game:GetService("MarketplaceService")

local player = Players.LocalPlayer --This is what is needed

local button1 = script.Parent.Donate1.SurfaceGui.TextButton

local product1 = 616014127

local function PromptPurchaseOnClick()
	market:PromptPrudctPurchase(player, product1)
end

--Omitted position parameters here since we don't need them at all
button1.MouseButton1Down:Connect(PromptPurchaseOnClick)

I recommend trying to organize your variable names. Here are further articles to help you with Developer products:

###Let me know if anything is wrong or if you had any other question.

I have fixed this buy replacing the text buttons with click detectors. I appreciate you all trying to help.
