if this error related to adding item, it should throw exception in your repository. So you need to catch it from calling service (or re-throw if you need to take some data in exception).
If the data corrupted and you can check it before an actual request, then validation is what you need. Validation should be is early as could be.
Also, I personally recommend to return wrapper in your repository. So in calling service you just need to check:

this approach can be done with many libraries or you create your own
