To resolve the "Invalid file url" error in the preview chatflow logs for Dify version 0.14.2 in a self-hosted environment, ensure that the FILES_URL environment variable is correctly configured in your docker-compose.yaml file. This variable should be set to a valid base URL pointing to where your files are hosted. For example, if your files are accessible at http://yourdomain.com/files, update the configuration as follows:

FILES_URL: 'http://yourdomain.com/files'

After making this change, restart your Dify services to apply the updates ^[1].
