We identified and fixed a bug affecting PDF generation that was causing the “Failed to generate PDF due to invalid HTML / missing image” error.

**What was the issue?**

A recent code update introduced a regression in our PDF generation error-checking logic. When validating image references in your documents, the system had an off-by-one error that caused valid documents to be incorrectly rejected.

**What we did:**

Our development team identified the root cause and deployed a fix to all Gigbuilder servers on May 22, 2026. The error checking logic now works correctly.

**What you need to do:**

Nothing — the fix is automatic. Just try generating PDFs as normal, and they should work without errors.

**Still having issues?**

If you’re still seeing PDF generation errors after May 22, please let us know. Reply to this topic or contact us via the support form.

Thanks for your patience!
