Error code 3 indicates that the .zip file structure is invalid or corrupt, so the message cannot be extracted. ArchiveOne validates data as it is committed to the archive so the corruption has occurred at a later date. If you have an earlier backup of the .zip file in question, you can restore this backup copy as it may be prior to the corruption. It is recommended you run a disk check of the storage hosting the ArchiveOne repositories to detect and resolve and issues.
