Knowledge Base API Interface: Error Creating Document from File

Error when uploading files to DIFY knowledge base via API:

API endpoint: document/create-by-file

Error message:

{
    "code": "invalid_param",
    "message": "Invalid user account",
    "status": 400
}

Uploading documents via text works normally using the same method. Therefore, the issue may be related to the API key used in the integration.

Note: DIFY version is 1.9.0. The same method worked in version 1.8.0. Could this be due to outdated API documentation not being updated to the latest version?

process_rule has been changed to a required field, but the documentation has not been updated.
