TFS 1.X+ I can't display print() in the server log.

Logs don't appear as expected in my terminal. When trying to display a log from a Lua script using print(), it doesn't show correctly in my terminal; the log is only displayed when my character logs out.

Example:

This is my talkaction place_monster.lua. I added a print() intending to display it when executing the talkaction, but it doesn't happen as expected.

function onSay(player, words, param)

    print("test")

    if not player:getGroup():getAccess() then
        return true
    end

    if player:getAccountType() < ACCOUNT_TYPE_GOD then
        return false
    end

    local position = player:getPosition()
    local monster = Game.createMonster(param, position)
    if monster then
        monster:getPosition():sendMagicEffect(CONST_ME_TELEPORT)
        position:sendMagicEffect(CONST_ME_MAGIC_RED)
    else
        player:sendCancelMessage("There is not enough room.")
        position:sendMagicEffect(CONST_ME_POFF)
    end
    return false
end

In the game, I execute the talkaction, and nothing shows in the terminal; it only shows when I log out.

I'm using TFS 1.4.2 release, and my server is inside WSL with Docker.

Check if the output is being buffered either by docker or wsl.

My Docker was indeed buffering the logs. When configuring the Docker image, I had to force it not to buffer the TFS logs.
