I am using the code sample provided in the below link:
The document is loaded with annotations correctly in the PDF viewer. However, when I export the annotations again, the TextMarkupContent attribute is missing/null in the exported xfdf/json file.
If you add a new annotation in the loaded document and export the annotations as xfdf/json file, the TextMarkupContent attribute is showing correctly for newly added annotation. But, for the annotations loaded along with the document is still missing.
Please let me know how to resolve this issue.
