Reindexing of OCFL id failed

[Bhavna Gehlot]

We migrated the OCFL-root to the S3 and few objects are giving issues like below exception.

We tried to do rebuild index and it gave the same issue.

I would appreciate if somebody can suggest how to resolve this issue?

rebuild stopped after the error:  ERROR 19:48:53.299 [ScheduledTask1] (ReindexManager) Reindex did not complete successfully
INFO 19:48:53.300 [ScheduledTask1] (IndexBuilderImpl) Index rebuild completed 841 objects successfully and 1 objects had errors in 7 mins, 56 seconds

I hit something like this, and resolved it by updating to latest Fcrepo.
