Export to pdf not working

[Xuwznln]

Steps to reproduce

1. Open diagrams.net with self-hosted Nextcloud (draw.io app).
2. Create any diagram.
3. File → Export as → PDF.

Expected
PDF is generated and downloaded (same as on https://app.diagrams.net/).

Actual
New tab opens https://convert.diagrams.net/node/export → blank page, no download.

Environment

• Nextcloud: 31.0.9
• draw.io app: 3.1.1

Found the same here. My workaround is to copy the document into diagrams.net and export the pdf from there

same issue, but I'm on Nextcloud 32.0.2 and draw.io app 3.1.2
