As far as I understand, some checks for ‘action’ are needed. But where and what exactly, i cant figure out

You should probably post the problem code too so we can try and debug it

controller

function on_input(self, action_id, action)
	local screen = vmath.vector3(action.x, action.y, 0)
	local world = camera.screen_to_world(CAMERA_ID, screen)
	action.x = world.x
	action.y = world.y
	msg.post("#cursor", "input", { action_id = action_id, action = action })
end

function on_message(self, message_id, message, sender)
	if message_id == cursor.OVER then
		print("Cursor over", message.id, message.group, message.x, message.y)
		self.over = message.id
	elseif message_id == cursor.OUT then
		print("Cursor out", message.id, message.group, message.x, message.y)
		self.over = nil
	elseif message_id == cursor.PRESSED then
		print("Pressed", message.id, message.group, message.x, message.y)
	elseif message_id == cursor.RELEASED then
		print("Released", message.id, message.group, message.x, message.y)
	end
end

player

function on_input(self, action_id, action)
	if action_id == CONTROLS.UP then
		self.velocity.y = SPEED
	elseif action_id == CONTROLS.DOWN then
		self.velocity.y = -SPEED
	elseif action_id == CONTROLS.LEFT then
		self.velocity.x = -SPEED
		player_flip(self)
	elseif action_id == CONTROLS.RIGHT then
		self.velocity.x = SPEED
		player_flip(self)
	elseif action_id == CONTROLS.INTERACT and action.pressed then
		interact(self)
	elseif action_id == CONTROLS.SPEED_1 then
		msg.post("main:/go#main", "change_speed", { amount = NORMAL_SPEED })
	elseif action_id == CONTROLS.SPEED_2 then
		msg.post("main:/go#main", "change_speed", { amount = FAST_SPEED })
	elseif action_id == CONTROLS.SPEED_3 then
		msg.post("main:/go#main", "change_speed", { amount = VERY_FAST_SPEED })
	end
end

defold-input cursor.script

local function handle_input(self, action_id, action)
	-- ignore accelerometer
	if not action_id and action.acc_x then
		return
	end
	action_pos.x = action.x
	action_pos.y = action.y
	self.action = action
	-- mouse movement
	if not action_id then
		go.set_position(action_pos)
		-- click or finger touching screen
	elseif action_id == self.action_id then
		if action.pressed then
			self.touch = true
			self.pressed = true
			self.skip_frame = true
		elseif action.released then
			self.touch = false
			self.released = true
			self.skip_frame = true
		end
		go.set_position(action_pos)
	end
end

function on_input(self, action_id, action)
	-- we should only care about calls to on_input if we have specifically acquired input focus
	-- if we haven't acquired input focus it is expected that input is sent via on_message from
	-- some other script
	if self.acquire_input_focus then
		handle_input(self, action_id, action)
	end
end

error in cursor.script
25 line

	action_pos.x = action.x
	action_pos.y = action.y
	self.action = action

337 line

	if self.acquire_input_focus then
		handle_input(self, action_id, action)
	end

I think the action check here is to see whether action.x exists for the input. Some actions do not include this variable, so you’re passing a nil variable (the non-existent action.x) to a vector when it wants a number. I recently just had a similar issue.

Thanks for the tip, I was able to fix the error
