Generating Svg for page

Error message

Generating Svg for page {i} failed, returned None.

What it means

Guard in export_doc_pages_as_bitmap_bytes: the DocPagesExportPrefs export format is set to a non-bitmap (Svg) variant, so bitmap export cannot proceed. Documented contract: this function errors unless the format pref is a bitmap variant (Png/Jpeg).

Solutions

1. Set doc_pages_export_prefs export format to Png or Jpeg before calling.
2. Use export_doc_pages_as_svgs_bytes instead when a vector export is intended.
3. When overriding prefs, pass DocPagesExportPrefs with a bitmap export_format.
