Need help printing on roblox server to local?

The simplest way to do this is to use a remote function as this will also work with fe. This will allow us to send the string names of what the processing finds. We cannot send the objects unless both sides have access to them e.g. parts in the workspace.

Example using remote functions:-

-- setup of the remote function
local remoteFunction = Instance.new('RemoteFunction', game:GetService('ReplicatedStorage'))
remoteFunction.Name = 'test'

function remoteFunction.OnServerInvoke(plr, getChildren, ...)
    local args = {...} -- ... indicates variable number of arguments

    -- check length
    if #args == 0 then return {'No args passed'} end

    local tmpTabl = {}
    local tmpData = game -- we start at game but we could start at another place 

    for i=1, #args do
        if tmpData:FindFirstChild(args[i]) then -- loop and try to get each child
            tmpData = tmpData:FindFirstChild(args[i])
        else
            -- we found a nil
            return {'Endpoint is nil'}
        end
    end

    if getChildren then
        for _, v in pairs(tmpData:GetChildren()) do -- get all children
            table.insert(tmpTabl, tostring(v))
        end
    else
        table.insert(tmpTabl, tostring(tmpData))
    end

    -- return result to the local script
    return tmpTabl
end

Local script example:-

local remFunc = game:GetService('ReplicatedStorage'):WaitForChild('test')

print('from server', unpack(remFunc:InvokeServer(false, 'Workspace','Part')))
print('from server', unpack(remFunc:InvokeServer(true, 'Workspace','Part')))
print('from server', unpack(remFunc:InvokeServer(true, 'ServerStorage','Padasd')))
print('from server', unpack(remFunc:InvokeServer(true, 'ServerStorage','Part')))

This is just my test setup.

You can also send the logs to the client. This would also use the same method of a remote function to pass back the logs to the client.

I hope this demo shows how this can be used. You should be able to adapt and change this to provide the functionality you need.

Please comment if you do not understand how / why this code works.
