What does "no error" mean when writing to a file in Lua?

I am writing a script to add one line in a .txt per video while using MPV.

However, I am getting a weird error on line 68 with the for loop. It merely tells me: no error. If I add an error parameter to file:write(message, error), it gives me another error message, stating: bad argument #2 to 'write' (string expected, got function). Any help would be appreciated.

function on_file_end(event)
    if not paused then totaltime = totaltime + os.clock() - lasttime end
    local message = (totaltime .. "s, " .. timeloaded .. ", " .. filename)
    local lines = {}
    local file = io.open(logpath, "r+")
    if file_exists(logpath) then
        for l in file:lines() do 
            if not l:find(message, 1, true) then
                lines[#lines+1] = 1
                file:write(message)
            end
        end
        file:close()
    end
end

error is not an "error parameter" it is a global function that allows to raise your own errors in Lua.

See https://www.lua.org/manual/5.4/manual.html#pdf-error
