OS version (server)	Ubuntu Server 20.04
TheHive version / git hash	4.1.1, upgraded from 4.0.5
Package Type	DEB

Problem Description

Following an upgrade from 4.0.5 to 4.1.1, all the attachments (images, .msg emails, etc.) that were included in task logs of old cases have disappeared.

[H2Cyber]

The attachments seem present on disk (under casefiles/attachment), but are completly absent in the GUI, which is a bummer (as we use attachments to add valuable investigation data to cases).

Let me know if I can provide anything to help troobleshoot.

Is this a duplicate of #1875 ?

What type of storage provider do you use?

What type of storage provider do you use?

## Database configuration
db.janusgraph {
  storage {
    backend: cql
    hostname: [
      "127.0.0.1"
    ]
    cql {
      cluster-name: thp
      keyspace: thehive
      read-consistency-level: ONE
      write-consistency-level: ONE
    }
  }
    # Index configuration
    index {
      search {
        backend: lucene
        directory: /data/thehive/index
      }
    }
}

## Attachment storage configuration
storage {
  provider: localfs
  localfs.location: /data/thehive/casefiles
}

Very likely yes, then I guess it should be fixed in 4.1.2

@To-om if this is duplicate of #1875 please just label it as duplicate

[To-om]

It is not the same issue. In #1875 logs disappear, not the attachments.

[nadouani]

@Aim4r what about file observable attachment? and user avatars? Are you still seeing them? And what's the exact error logs you have?

[To-om]

@Aim4r can you confirm that file permission are correct (user thehive must have read/write access).
The attachments have disappeared or they is an error while retrieving ?

[H2Cyber]

In my case the attachments are all included as part of task logs.
So if the old task logs do not appear in 4.1.1, then my attachments won't appear either.
