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

1. The workflow is published as a tool and the output variable files cannot fetch the file - This discussion is still open and might provide insights into handling file outputs in workflows ^[1].

2. How can I output a file in Workflow - This discussion is also open and addresses issues related to file outputs in workflows ^[2].

Regarding your issue, when deploying a workflow as a web app, Dify processes file outputs by checking if they contain files with a specific identity (__dify__file__). These files are then displayed in a FileList component, allowing users to download or preview them. If the files are not appearing, it might be due to a misconfiguration or an issue with how the files are being processed in the deployed environment ^[3].

Additionally, ensure that your self-hosted setup is correctly configured for file export. You need to set the FILES_URL parameter in the docker/.env file to match your Dify access address, and verify that the volumes section in your docker-compose-template.yaml file includes a mount for the storage directory to the container ^[4][5].
