API for trello works in studio but not the game?

I made a Trello API using nstrike159's script. It works in the studio and makes new cards when I clicked the button in the studio but, when I join the game it won't do anything. Any suggestions on how I could fix this? Filtering enabled is off by the way.

The in game logs say

1. OnServerInvoke can only be implemented on the server
2. OnServerEvent can only be used on the server

ServerLog: Content failed because HTTP 404

local Name = script.Parent.Parent.Information.LOLNAME
    local Evidence = script.Parent.Parent.Information.Evidence.Text
    local Witness = script.Parent.Parent.Information.Witnesses.Text
    local TimeDate = script.Parent.Parent.Information.TimeDate.Text
    local Addition = script.Parent.Parent.Information.AdditionalComments.Text
    local Updates = script.Parent.Parent.Information.Update.Text
api = require(game.Workspace.TrelloAPI)
local BoardID = api:GetBoardID("LVPD Detective Database v2")
local ListID = api:GetListID("Cases Pending Distribution",BoardID)

    end)
end)
