Networking an Ability spawned from client, context error

Help
1

I'm trying to make a system where I can play any player animations whenever I want without using weapons/equipment, but when I try to call a function inside a networked script from a client script in multiplayer preview mode, I get this error:

LocalPlayerBindingManagerScript:5: attempt to index a nil value (field 'context')

The two scripts work in normal Play mode.

First script:

local propNetworkAnimationScript = script:GetCustomProperty("NetworkAnimationScript"):WaitForObject()
local player = Game.GetLocalPlayer()

function OnBindingPressed(player, action)
    propNetworkAnimationScript.context.AbilityAnimation(player, action)
end

player.bindingPressedEvent:Connect(OnBindingPressed)

Second script, networked and assigned to first scripts custom property:

local propUnarmed_Magic_Bolt = script:GetCustomProperty("Unarmed_Magic_Bolt")
local propOneH_Slash_Right = script:GetCustomProperty("OneH_Slash_Right")

function AbilityAnimation(player, action)
    if (action == "ability_primary") then -- Mouse 1
        -- Cast ability on 1
        local ability = World.SpawnAsset(propUnarmed_Magic_Bolt)
        ability.owner = player
        player:GetAbilities()[1]:Activate()
        ability:Destroy()
    end

    if (action == "ability_secondary") then -- Mouse 2
        -- Cast ability on 2
        local ability = World.SpawnAsset(propOneH_Slash_Right)
        ability.owner = player
        player:GetAbilities()[1]:Activate()
        ability:Destroy()
    end

    if script.isNetworked then
        print("It is networked!")
    end
    -- print(#player:GetAbilities()) Test to see if Abilities are deleted
end
