Handle cases where CDP's file upload service can't find the upload ID

Proposed change

Jira ticket: https://eaflood.atlassian.net/browse/DF-834

Type of change

This PR addresses issues where CDP's file upload service can return 404 for a given upload ID. This usually occurs when a user is returning to a save-and-exit submission after more than >1 week. CDP's file upload service only has a Redis TTL of 1 week, so it needs handling.
