It looks like you’re trying to require the Manager module from the PlayerData folder in ServerScriptService. However, based on the error message you provided, it seems that the Manager module either doesn’t exist or is not properly located in the PlayerData folder.
To fix this issue, you should double-check that the Manager module exists in the correct folder and that the module script is named correctly (i.e. “Manager”). You should also make sure that there are no typos in the folder or module names.
Assuming that the Manager module exists in the PlayerData folder, you should be able to require it using the following code:
local dataManager = require(game:GetService("ServerScriptService").PlayerData.Manager)
If the issue persists, you can try printing out the contents of the ServerScriptService and PlayerData folders to verify that the module is located in the correct folder.
The ServerScriptService basically is something that will keep certain things deep down inside of your game. For example, it is good to do this just incase of exploiters ruining the game. Some exploiters wouldn’t be able to dig deep down into those files, including the ones in ServerScriptService or ServerStorage. If you have your modulescript inside of SSS, then it should work fine. Otherwise, if your modulescript that is trying to require another module is outside of SSS, then it wouldn’t be possible for your modulescript to require something from SSS.
