To resolve the issue where Dify is unable to reference picture URLs due to a missing 'http://' or 'https://' protocol, resulting in a '400 Bad Request' error, ensure that all image URLs include the required protocol prefix ('http://' or 'https://'). This is a known limitation in Dify 0.15.3 when running in a self-hosted Docker environment. Additionally, consider using cloud-hosted images instead of local uploads to avoid this issue ^[1][2].

Make sure your FILES_URL is correctly set with the appropriate protocol in your configuration.
