What happens to failed flow interviews for standard flows?

For standard flows in Salesforce, when a flow interview fails, it is not saved. This means that any execution of the flow that encounters an error or an issue resulting in failure is discarded and cannot be retrieved for future examination or debugging. Since the data and context of that flow interview are not retained, this emphasizes the importance of designing flows with error handling in mind, allowing administrators to guide the flow execution toward successful outcomes or to capture error details through logging or notification systems.

In contrast, other options suggest functionalities that do not apply to standard flows. For example, the idea that failed interviews might be saved for a certain period or that they can be retried automatically implies a level of retention and automatic processing that does not exist in standard flow behavior within Salesforce. Each flow execution is considered independent, and thus, prior failed executions do not impact subsequent attempts.
