Hi @Itai M.,

🙂 You question is little bit philosophical. Main subpart of your question could be is there some failure at all?!

In general software exception is a way some function/method (or generally code piece) to return alternative result to calling code. What will be this alternative result? 🤔 Could be anything. Very common is such result to be used as error/failure signal, but this is not mandatory. Interpretation of such alternative result is matter of context. 😉

In your particular case the "failure" is preexistence of the link your are trying to create. Is this a real failure or something acceptable? 🧐 It depends on your application design (i.e. your desire).

How can you handle that? If according to your initial idea preexistence of such link is unexpected..., one way is to signal to the user, for example. Otherwise, you can catch the exception and pop wanted result out from there - there is a "metadata" field matching exactly the normal result when this type of exception gets catch (from that point on you can continue normal application flow). 😉 So finally... the choice is yours.

Hope this helps.

@Itai M. That's correct, if there's already a shared link for the item, you'll get that 'shared_link_already_exists' error. You can catch and handle that exception as needed. You can also use listSharedLinks to check for/list existing shared links.
