If you want to be canonical about it, you should be using pcall for all methods (not events) of MarketplaceService because in the end they’re all web calls. It’s not all-important though: you probably don’t need to do error handling for this and it’s important that if MarketplaceService fails you know what the error is so that you can file a bug report. Roblox functions that perform web calls should have a low fail rate but they definitely fail more than they should.
If you ask me though, I don’t pcall any MarketplaceService functions.
