I had an issue when exporting a Threat actor group. Then the entity could not be accessed anymore on the plateform with the same error. Here's the log:

"TypeError: Cannot read properties of undefined (reading 'metaData')",
      "at /home/tom/softwares/filigran/opencti/opencti-platform/opencti-graphql/src/database/file-storage.js:357:27",
      "at Array.sort (<anonymous>)",
      "at resolveImageFiles (/home/tom/softwares/filigran/opencti/opencti-platform/opencti-graphql/src/database/file-storage.js:356:6)",
      "at filesListingFn (/home/tom/softwares/filigran/opencti/opencti-platform/opencti-graphql/src/database/file-storage.js:312:21)"

Maybe it's nothing, I'll try reproducing the issue and give update.

UPDATE: I could reproduce the error. Basically, it works well until the connector is reset (as shown in the screenshot). After, the backend starts firing traces when accessing the entity, fails and end with the above error. I did not dig the code to see what caused the bug, but it works well on master.

I keep reproducing the error on my side, exporting a threat actor group (or individual) after resetting the connector yields the following response from the API, the export never finish and the entity can't be accessed anymore.

{
  "errors": [
    {
      "message": "Cannot read properties of undefined (reading 'metaData')",
      "locations": [
        {
          "line": 14,
          "column": 3
        }
      ],
      "path": [
        "stixCoreObject",
        "exportFiles"
      ],
      "extensions": {
        "code": "INTERNAL_SERVER_ERROR",
        "exception": {
          "stacktrace": [
            "TypeError: Cannot read properties of undefined (reading 'metaData')",
            "    at /home/tom/softwares/filigran/opencti/opencti-platform/opencti-graphql/src/database/file-storage.js:357:27",
            "    at Array.sort (<anonymous>)",
            "    at resolveImageFiles (/home/tom/softwares/filigran/opencti/opencti-platform/opencti-graphql/src/database/file-storage.js:356:6)",
            "    at filesListingFn (/home/tom/softwares/filigran/opencti/opencti-platform/opencti-graphql/src/database/file-storage.js:312:21)"
          ]
        }
      }
    }
  ],
  "data": {
    "stixCoreObject": {
      "__typename": "ThreatActorIndividual",
      "__isStixCoreObject": "ThreatActorIndividual",
      "id": "8bae4557-c98d-411b-99dc-ae556776fbf3",
      "exportFiles": null
    }
  }
}

But we tested it on @marieflorescontact environment and it indeed didn't show up. Can someone else try to reproduce the error? We will be able to tell whether the issue is with my config or with the code. I'm available if further instruction is needed.

@marieflorescontact @RomuDeuxfois is this PR fixing all types of export not displaying the "spinning" wheel?

1. Go to https://testing.octi.staging.filigran.io/dashboard/analyses/reports/246a8e25-6b42-4c4d-a9bb-20e2a94803e8/files
2. Export in JSON
3. Line disappears until export is done (during 1 minutes)
