Trouble with weapon and Ignite method

[MGCLegend]

Hello, good day to you.

I am having a problem with an error that my weapon throws when it ignites the player.
It successfully ignites the player but it also throws an error that it cannot call the method 'Ignite'

Copy of code in question:

function SWEP:SecondaryAttack()
	pos = self.Owner:GetShootPos()
	ang = self.Owner:GetAimVector()
	vm = self.Owner:GetViewModel()
	if self:CanPrimaryAttack() and self.Owner:IsPlayer() then
	self.Weapon:SendWeaponAnim( ACT_VM_IDLE )
		if !self.Owner:KeyDown(IN_SPEED) and !self.Owner:KeyDown(IN_RELOAD) then
			local stab = {}
			stab.start = pos
			stab.endpos = pos + (ang * 24)
			stab.filter = self.Owner
			stab.mins = Vector(-10,-5, 0)
			stab.maxs = Vector(10, 5, 5)
			local stabtrace = util.TraceHull(stab)
			if stabtrace.Hit then
				vm:SetSequence(vm:LookupSequence("stab"))
			else
				vm:SetSequence(vm:LookupSequence("stab_miss"))
			end
			
			timer.Create("cssstab", .33, 1 , function() if not IsValid(self) then return end
			if IsValid(self.Owner) and IsValid(self.Weapon) then 
				if self.Owner:Alive() and self.Owner:GetActiveWeapon():GetClass() == self.Gun then 
					self:Stab() end
				end
			end)

			self.Owner:SetAnimation( PLAYER_ATTACK1 )
			self.Weapon:SetNextPrimaryFire(CurTime()+1/(self.Primary.RPM/60))
			self.Weapon:SetNextSecondaryFire(CurTime()+1.25)
		end
	end
end

function SWEP:Stab()

	pos2 = self.Owner:GetShootPos()
	ang2 = self.Owner:GetAimVector()
	damagedice = math.Rand(.85,1.25)
	pain = 100 * damagedice
	self.Owner:LagCompensation(true)
	local stab2 = {}
	stab2.start = pos2
	stab2.endpos = pos2 + (ang2 * 24)
	stab2.filter = self.Owner
	stab2.mins = Vector(-10,-5, 0)
	stab2.maxs = Vector(10, 5, 5)
	local stabtrace2 =  util.TraceHull(stab2)

	if IsValid(self.Owner) and IsValid(self.Weapon) then
		if self.Owner:Alive() then if self.Owner:GetActiveWeapon():GetClass() == self.Gun then
			if stabtrace2.Hit then
			targ = stabtrace2.Entity
				if targ:IsPlayer() or targ:IsNPC() then
					paininfo = DamageInfo()
					paininfo:SetDamage(pain)
					paininfo:SetDamageType(DMG_SLASH)
					paininfo:SetAttacker(self.Owner)
					paininfo:SetInflictor(self.Weapon)
					local statues = ents.FindByClass("pdstatue")--FIND ALL PDSTATUES HERE
					
					for k, v in pairs(statues) do --FOR ALL PDSTATUES FOUND DO:

						local distance =  self.Owner:GetPos():Distance(v:GetPos()) -- GET DISTANCE FOR THIS STATUE
						
						if distance < 100 && self.Owner:IsValid() then --IF THE DISTANCE FOR THIS STATUE IS LESS THAN 100 UNITS
						
							self.Owner:SetHealth(666)
							self.Owner:Ignite(666) --WHERE WE IGNITE THE PLAYER
							self.Owner:setGodlike(true)

						end
					
					end

					paininfo:SetDamageForce(stabtrace2.Normal *75000)
					if SERVER then targ:TakeDamageInfo(paininfo) end
					self.Weapon:EmitSound(self.KnifeStab)//stab noise
				else
					self.Weapon:EmitSound(self.KnifeShink)//SHINK!
					look = self.Owner:GetEyeTrace()
					util.Decal("ManhackCut", look.HitPos + look.HitNormal, look.HitPos - look.HitNormal )
				end
			else
				self.Weapon:EmitSound(self.Primary.Sound)
			end
		end end
	end
	self.Owner:LagCompensation(false)
end

Copy of error:

[ERROR] addons/sacrificemod/lua/weapons/sacrifice_knife/shared.lua:231: attempt to call method 'Ignite' (a nil value)
  1. Stab - addons/sacrificemod/lua/weapons/sacrifice_knife/shared.lua:231
   2. unknown - addons/sacrificemod/lua/weapons/sacrifice_knife/shared.lua:186

Timer Failed! [cssstab][@addons/sacrificemod/lua/weapons/sacrifice_knife/shared.lua (line 183)]

Just wondering why it gives the error so I I can make it go away.
Even so it still ignites the player with the same line of code?
And yes I'm using m9k as a base. -Don't judge me pls.
