This is probably due to missing indexes on rocketchat_upload’s collection.

You could check your indexes with:

  1. connect to mongo:
    docker compose exec -it mongo mongo mongo/rocketchat
  2. Execute:
    db.rocketchat_uploads.getIndexes()

you should have something like this:

[
	{
		"v" : 2,
		"key" : {
			"_id" : 1
		},
		"name" : "_id_"
	},
	{
		"v" : 2,
		"key" : {
			"name" : 1
		},
		"name" : "name_1",
		"sparse" : true
	},
	{
		"v" : 2,
		"key" : {
			"rid" : 1
		},
		"name" : "rid_1",
		"sparse" : true
	},
	{
		"v" : 2,
		"key" : {
			"uploadedAt" : -1
		},
		"name" : "uploadedAt_-1"
	},
	{
		"v" : 2,
		"key" : {
			"rid" : 1,
			"_hidden" : 1,
			"typeGroup" : 1
		},
		"name" : "rid_1__hidden_1_typeGroup_1"
	}
]

If not, you probably need to add new indexes or run migrations.

In case you have missing indexes, try creating this index.

db.rocketchat_uploads.chunks.createIndex( { files_id: 1, n: 1 }, { unique: true } )
