About the file upload in API

[sandycs-protoss]

The workflow supports file upload functionality, but how do I pass the file when calling the API? It seems that the files field in the API is not recognized by the workflow system.
Below is the data I used to send to the API. The image_file is a variable I've set in the start of the workflow
{
"inputs": {
"image_file":"https://img.calceus.org/wechat/2053058426234668218.png?x-oss-process=image/resize,w_1500"
},
"query": "Analyse this picture for me",
"response_mode": "blocking",
"conversation_id": "",
"auto_generate_name": false,
"user": "wechatbot",

"files": [
{
"type": "image",
"transfer_method": "remote_url",
"url": "https://img.calceus.org/wechat/2053058426234668218.png?x-oss-process=image/resize,w_1500"
}
]
}

Hey @sandycs-protoss! I'm here to help you with any bugs, questions, or contributions you have. Let's tackle this together!

To pass a file when calling the API in a workflow system where the files field is not recognized, you should create a custom file variable in the "Start" node of your Workflow application. This allows you to upload, parse, and reference files as File variables within the workflow. You can choose either a "Single File" or "File List" as the field type for the variable. After uploading, use a "Document Extractor" node to convert the file content into a format that can be processed by LLMs. This approach is recommended as the sys.files variable is marked as LEGACY and will be deprecated in the future ^[1][2].
