pathfinding not finding a path for some reason?

Your script will only run once so what you need to do is put the pathfinding script inside a while loop like this

wait(1)
local plr = game.Players.LocalPlayer
local char = plr.Character

while wait(1) do -- it will create a new path every 1 second, you can change it
local pathfind = game:GetService("PathfindingService")

local p1 = pathfind:FindPathAsync(char.LowerTorso.Position,workspace.ptgt.Position)

if p1.Status == Enum.PathStatus.Success then
    for i,v in pairs(p1:GetWaypoints())do
        char.Humanoid:MoveTo(v)
        char.MoveToFinished:Wait()
        if v.Action == Enum.PathWaypointAction.Jump then
            char.Humanoid.Jump = true
        end
    end
else print "no path"
end
end

When the game runs, the script will check if there is anything nearby to move to and if there isn't, then the script will just stop since it ran only once.
