AWS S3 repeats first item in search with prefix

[leesilverman]

Bug Description

Looks like for whatever reason the AWS s3 module is just using the first item over and over again instead of looping through all items.

Prefix option is set to use a value from the input. Input has 3 items. The folder (prefix) for the first item has 9 objects. The output has 27 objects. It's the 9 objects from the first item, repeated 3x - once for each input item.

{ "meta": { "instanceId": "56a3b6e808c84fdadd2d80585289500a7b27625c2792fc6c214518fe7ce0a003" }, "nodes": [ { "parameters": { "resource": "bucket", "operation": "search", "bucketName": "wrd-media-archive", "returnAll": true, "additionalFields": { "prefix": "=instagram/{{ $json.id }}" } }, "id": "6db668ef-823d-4fdc-b267-e64c998e3f7d", "name": "List wrd-media-archive-directory", "type": "n8n-nodes-base.awsS3", "typeVersion": 2, "position": [ 1800, 1040 ], "credentials": { "aws": { "id": "xT7Ztjk2dBmYX3TD", "name": "Lee WRD AWS API Key access" } } } ], "connections": {}, "pinData": {} }

To Reproduce

1. Create a dummy/test bucket
2. Create an S3 folder named "test"
3. Create 4 subfolders in test named a, b, c, d
4. In each subfolder, upload a few files, but make sure they're different so you can distinguish the file contents of a vs b vs c
5. Create an input with 4 items: id="a", "id="b", etc
6. Set the AWS S3 module to "Search" and set the prefix option to "test/{{$json.id}}

If you reproduce the bug, you'll see the objects in subfolder a 4x in the output, instead of seeing separate results for each input row.

Expected behavior

All items in the input should be processed. Ideally there's a 1-1 correspondence, where one input row = one output row with an array of search results or empty if there are no results.
