NotFoundError: During updating of a single RECAPDocument in ES.

[sentry-io]

This issue has occurred once so far and seems ok. Perhaps we could just catch the error and log a warning to avoid sending it to Sentry.

I reviewed it, and the RECAPDocument had indeed been removed from the database.

It happened during the upload of an HTML report:
https://www.courtlistener.com/admin/recap/processingqueue/13228143

What likely occurred is that the RECAPDocument was duplicated, and the duplicate was removed during the add_docket_entries process. What is strange is that the RECAPDocument was updated and immediately removed, possibly due to a race condition or something similar.

So far the entry now looks correct and properly indexed in ES:
