Code node Binary output tab disappeared - regression between April 21-22, 2026

Problem

The Binary tab in Code node output disappeared overnight. Same workflow that displayed binary images yesterday now shows no Binary tab at all.
Timeline:

  • April 21, 2026: Binary tab visible, images display correctly in output panel
  • April 22, 2026 (~24 hours later): Binary tab completely gone, only JSON visible
    Same workflow, same code, same API responses — but Binary tab is no longer rendered.
    Node executes with green checkmark (success) but the Binary tab that previously appeared is completely hidden.

System Info

  • n8nVersion: 2.15.0
  • platform: docker (cloud)
  • binaryMode: filesystem
  • nodeEnv: production

Expected vs Actual

Expected: Binary tab appears with downloadable files
Actual: Binary tab is missing, only JSON schema/table/JSON tabs visible
This appears to be a regression from a recent n8n update. Has anyone else experienced this in the last 24 hours?

Binary tab vanishing after an update is usually a browser caching issue first — hard reload (Ctrl+Shift+R / Cmd+Shift+R) and clearing cached assets often brings it back.

If that doesn’t help with Docker + filesystem binaryMode, worth checking whether the binary data directory is still correctly mounted after the update — we’ve seen cases where a volume path mismatch silently broke the tab rendering. Also a good one to open as a GitHub issue since you have the exact regression date range.

@Vaszer this is almost certainly a frontend build cache issue on the docker image, not your workflow — the binary data is still there, the tab just isn’t rendering. try pulling a fresh image with docker pull n8nio/n8n:latest and recreating the container, that forces the UI assets to rebuild. to confirm the binary data is actually intact, import this and point it at one of your image URLs:

if the Binary tab shows on that test workflow but not yours, the issue is in how your Code node returns the binary — if it’s missing on both, it’s the container image and a repull fixes it.
