Any updates on this??
From my own experience of using Figma’s AI tool, I tried to generate a visual storyboard project, all uploaded images and GIFs appear correctly within the editor. However, when exporting a preview link via the “Share” or “Export Preview” button, the preview loads completely blank — all frames revert to “Drop image/GIF/video” placeholders.
Upon reviewing the generated code, it appears the export function is embedding all uploaded assets directly into the URL as base64 data (using btoa(JSON.stringify(frames))). This causes the generated preview link to exceed browser URL length limits. When the link is opened, the query string is truncated or rejected, resulting in the preview loading without any media content.
In short:
-
Assets display fine in the editor.
-
Preview links show no content (blank placeholders).
-
Duplicating, re-uploading, or using prototype links doesn’t resolve it.
-
The issue occurs for all collaborators — not a local or permission-related issue.
-
Root cause appears to be URL size overflow from base64-encoded image data embedded in the link.
Preview links should properly render uploaded assets, or large files should be handled through a temporary data store or asset reference instead of embedding data directly in the URL.
All storyboard previews using this AI-generated template are nonfunctional, preventing visual review and internal sharing.
This tool is entirely pointless until otherwise fixed on the backend..
