In version 1.18.1, when calling the https://api.dify.ai/v1/workflows/{workflow_id}/run API, I found that the file parameter gives an error. What could be causing this? Because the same parameter format worked fine in version 1.13.3.

I've correctly uploaded the file and got the file ID.

Here are the parameters I used to call the run API
[Object: {
"inputs": {
"files": [
{
"type": "document",
"transfer_method": "local_file",
"upload_file_id": "fc9dcfe5-251a-4aa2-a6e8-3c7587318992"

},
"response_mode": "blocking",
"user": "n8n-bot"
}
]

The response is Bad request - please check your parameters
Invalid upload file

PS:When I was uploading the file, the user value was also n8n-bot

2. Additional context or comments

No response

[g4lb]

Dify checks that the run user owns the file, and end users are per app.
Try to upload and run with the same app API key.

[Spell-maker-Y]

Can a user not exist? Why is it that when I use my Dify login account, there's still no user_id returned; is the fact that I didn't run the command "sudo docker compose exec api flask db upgrade" the direct cause of the problem?

[g4lb]

user_id is not the owner. The owner is created_by, so user_id: null is not the cause.

Which Dify version and deployment are in use, and were the upload and workflow-run requests made with the same app API key? Please include the redacted upload response and run request body, with file IDs and credentials removed.
