1. Is this request related to a challenge you're experiencing? Tell me about your story.

I am using ComfyUI tool generating several images, then I want to send those images one by one to the multimodal LLM, let the LLM descibe the content for me. Then I found that the iteration node can not deal with Array['files'], what can I do? Is there a way that I can select the items in Array by index, i.e. Files[iteration/indexnumber]?

2. Additional context or comments

invalid iterator value: value_type=<SegmentType.ARRAY_FILE: 'array[file]'> value=[File(dify_model_identity='dify__file', id=None, tenant_id='ff222508-ecdf-4890-acdc-f8ec194a3628', type=<FileType.IMAGE: 'image'>, transfer_method=<FileTransferMethod.TOOL_FILE: 'tool_file'>, remote_url=None, related_id='dec4bafa-0281-4cfa-8c87-64f831c250cb', filename='f8266e5fc98e4aa3a8ab98445fc60928.png', extension='.png', mime_type='image/png', size=324017), File(dify_model_identity='dify__file', id=None, tenant_id='ff222508-ecdf-4890-acdc-f8ec194a3628', type=<FileType.IMAGE: 'image'>, transfer_method=<FileTransferMethod.TOOL_FILE: 'tool_file'>, remote_url=None, related_id='c7d620bc-4a2b-48e8-b431-c9f445eb369f', filename='b63247f3e20c4e678c6b9543bfbeacb9.png', extension='.png', mime_type='image/png', size=354757), File(dify_model_identity='dify__file', id=None, tenant_id='ff222508-ecdf-4890-acdc-f8ec194a3628', type=<FileType.IMAGE: 'image'>, transfer_method=<FileTransferMethod.TOOL_FILE: 'tool_file'>, remote_url=None, related_id='d1ddee8a-6ba7-4b56-a28d-2e8863583bb1', filename='4c285a3c95c0436483917d15ee1951c3.png', extension='.png', mime_type='image/png', size=346694)] id='74690aff-1a49-473d-a817-9fb492bfa201' name='files' description='' selector=['1736231102100', 'files'], please provide a list.

is there any difference between sys.files and ComfyUI.files?
