Remarks

In general, you cannot safely prevent these exceptions from happening. Conditions external to your code can cause failures. For this reason, you should always expect that an operation can fail.

Operation exception always contains a (non-null) inner exception. This is because it is thrown as a wrapper exception by single-operation methods, but multiple-operation methods return the inner exception through their results, and therefore the inner exception is the one that actually determines the error cause.
