Working on a pedestrian script and I am getting this cryptic error after running the ComputeAsync: 

sabuiltin_CollisionGroupsEditor.rbxm.CollisionGroupsEditor.AssetMain.main:206: attempt to index nil with 'CurrentDataModelTypeAboutToChange'

This is the function:


function Pedestrian.new(pointsToTraverse)
    local self = setmetatable({}, Pedestrian)

    -- Create pedestrian model and spawn at first point
    self.PedestrianModel = BasePedestrian:Clone()
    self.PedestrianModel.Parent = workspace
    self.PedestrianModel:SetPrimaryPartCFrame(CFrame.new(pointsToTraverse[1]))

    -- Create and run path
    local PedestrianPath = PathfindingService:CreatePath({
        AgentRadius = 2,
        AgentHeight = 5,
        AgentCanJump = false
    })
    
    PedestrianPath:ComputeAsync(self.PedestrianModel.PrimaryPart.Position, pointsToTraverse[2])

    local PedestrianWaypoints = PedestrianPath:GetWaypoints()
    for _, waypoint in pairs(PedestrianWaypoints) do
        self.PedestrianModel.Humanoid:MoveTo(waypoint.Position)
        self.PedestrianModel.Humanoid.MoveToFinished:Wait()
    end
    return self
end

Running debug, both arguments for the ComputeAsync are valid vector3s
