"IsA is not a valid member of Color3"

[jaxsreality (Cobratate)]

Hello. I ran into this issue while scripting, anyone know what this could mean? The output gives me the error “IsA is not a valid member of Color3” when I run the following code:

while true do

	for i, v in pairs(parts) do
		if v:IsA("Part") then

			Tween2:Play()

		end
	end

end

I am not using any Color properties in my code, just a part transparency tween. Why would this error show up?

Thanks for any help

Can you show how you’re defining ‘parts’ and populating it?

My apologies, should have provided more context.

The script is inside of a Part, which parents the “parts” which I want to modify the transparency of.

Part
Script
ChildPart
ChildPart
ChildPart
ChildPart
etc…

The way I’m defining parts is

local parts = script.Parent:GetDescendants()

Are you ever appending to the table after calling :GetDescendants? If parts is just an array of instances it shouldn’t error when you call :IsA on it.

As a last resort if nobody else chimes in and you can’t find the source, you can try something like if typeof(v) == 'Instance' and v:IsA('BasePart') then, or you could try iterating over the parts table and remove any members that aren’t Instances after populating it.

you could always do
“if typeof(v) == “Instance” and v:IsA(“Part”) then”
to avoid this error. But I recommend finding a reason a color3 would be put into that table since thats not intended by you.

Edit: Oops didnt notice above reply said the same thing.

Thank you for the help, @yoolurs as well.

I decided to simplify it a little and added the line you suggested, resulting in the following:

Script:

local parts = script.Parent:GetDescendants()


for i, v in pairs(parts) do
	if v:IsA("Part") then

		if typeof(v) == 'Instance' and v:IsA('Part') then



			v.Transparency = 1


		end
	end
end

Output:

Also here’s the setup in explorer:

EDIT: Figured it out, ty all for the help
the above script works and no longer errors
