My npc not properly moving to the face of a part?

I have an issue where I try to make an npc move to behind a part based on the normal. Here’s the code I have for finding the normal

function NormalToFace(normalVector, part)

    local TOLERANCE_VALUE = 1 - 0.001
    local allFaceNormalIds = {
        Enum.NormalId.Front,
        Enum.NormalId.Back,
        Enum.NormalId.Bottom,
        Enum.NormalId.Top,
        Enum.NormalId.Left,
        Enum.NormalId.Right
    }    

    for _, normalId in pairs( allFaceNormalIds ) do
        -- If the two vectors are almost parallel,
        if GetNormalFromFace(part, normalId):Dot(normalVector) > TOLERANCE_VALUE then
            return normalId -- We found it!
        end
    end

    return nil -- None found within tolerance.

end

function GetNormalFromFace(part, normalId)
    return part.CFrame:VectorToWorldSpace(Vector3.FromNormalId(normalId))
end

the code for actually calling the functions

local normalID = NormalToFace(ResultLeft.Position, ResultLeft.Instance)
print(normalID)
print(Vector3.FromNormalId(normalID))

local dir = Vector3.FromNormalId(normalID) * -10
moveTo(myRoot.CFrame:PointToWorldSpace(dir))
print(myRoot.CFrame:PointToWorldSpace(dir))

local Part = Instance.new("Part", workspace)
Part.Size = Vector3.new(1,1,1)
Part.Anchored = true
Part.Material = "Neon"
Part.BrickColor = BrickColor.new("Neon orange")
Part.Position = myRoot.CFrame:PointToWorldSpace(dir)
Part.Name = "MachineGunnerCoverPart"
Part.CanCollide = false

I want the npc to go like this:

but he goes like this:

image961×366 98.8 KB

If anyone could tell me what I’m doing wrong, it would be greatly appreciated!

Have you tried putting prints in to confirm the logic flows as you expect.
I see you have printed the result of normalid but what if its nil?
Perhaps print out the value returned from GetNormalFromFace;

I have done all of these things.
The parts that I create always appear at the position he moves to, and never where I want it to. It’s confusing

What is the value of ResultLeft and subsequent normalID?
