What is a common consequence if a flow URL references a specific version that has been deactivated or deleted?

When a flow URL references a specific version of a flow that has been deactivated or deleted, the expected outcome is that the flow generates an error and fails to execute. This is because the referenced version is no longer active or available in the system, which means that any attempt to call or execute this flow will result in an error indicating that the requested resource cannot be found or accessed.

By referencing a deactivated or deleted version, the system cannot locate the necessary components or logic that define how the flow is supposed to function, leading to a failure in execution. This reinforces the importance of keeping track of flow versions, especially in environments where flows may be frequently updated or modified. In contrast, the other options suggest scenarios where the flow would either update automatically, run with limitations, or notify an admin, none of which accurately reflect the behavior of Salesforce in this situation.
