@18075717849 Hello there! I'm here to help you with any issues, bugs, or questions you have about the Dify repository. I'll do my best to assist you while we wait for a human maintainer to address your concerns.

I found some similar discussions and issues related to file upload errors in Dify:

  1. Dify failed to upload a large PDF even though UPLOAD_FILE_SIZE_LIMIT has been set to a large value [1].
  2. 知识库上传文件报错 [2].
  3. Flexibility to change the file upload size on Embedding (closed) [3].

The suggested solution involves ensuring that both the UPLOAD_FILE_SIZE_LIMIT environment variable and the client_max_body_size parameter in the Nginx configuration are set correctly. Here are the steps to resolve the issue:

  1. Check UPLOAD_FILE_SIZE_LIMIT:
    Ensure that the UPLOAD_FILE_SIZE_LIMIT in your dify_config is set to a value larger than the file you are trying to upload. The default value is 15 MB [4].

  2. Update Nginx Configuration:
    Modify the client_max_body_size parameter in the Nginx configuration to match the desired upload limit. This can be done by setting the NGINX_CLIENT_MAX_BODY_SIZE environment variable in your Docker setup.

    Example:

    NGINX_CLIENT_MAX_BODY_SIZE=50M

    Update the docker-compose.yaml file:

    environment:
  NGINX_CLIENT_MAX_BODY_SIZE: ${NGINX_CLIENT_MAX_BODY_SIZE:-50M}

    Ensure the Nginx configuration template reflects this change:

    client_max_body_size ${NGINX_CLIENT_MAX_BODY_SIZE};

  3. Rebuild and Restart Docker Containers:
    After making these changes, rebuild and restart your Docker containers:

    docker-compose down
docker-compose up --build -d

These steps should help resolve the "413 Request Entity Too Large" error and allow you to upload files successfully [5][6][7].
