I found some similar discussions that might be relevant to your issue:

  1. I can't upload the image on dify workflow via api (open) [1].
  2. Where are the images and files generated by Dify stored? Also, the tool's API cannot access the generated files. (open) [2].
  3. 知识库上传文件报错 (open) [3].

Regarding your specific issue, yes, it is possible to have both a success and a failure when uploading files through the create_by_file API interface. The error "File not found" indicates that the specified file could not be located or accessed during the upload process. This error might also occur if there are issues with the deployment method or if the api/storage/privkeys directory has been deleted, as this file is used to encrypt large model keys [4][5].

To resolve the "File not found" error in a local deployment, you can reset the encryption key pair using the following commands:

  • Docker Compose Deployment:

    docker exec -it docker-api-1 flask reset-encrypt-key-pair

  • Source Code Deployment:
    Navigate to the api directory and run:

    flask reset-encrypt-key-pair

Follow the prompts to complete the reset process [4][5].
