## Additional Context
(Please add any additional context or steps to reproduce the error here)

Start by reproducing the attached Seedream 4 workflow and inspect the LoadImage nodes using input.png, especially node 15. Trace the asset lookup that reports "database: asset not found" and compare it with the uploaded 0_2.png input. Done means the workflow can retrieve its referenced input images and run without ImageDownloadError.
