Hello,

Thanks for providing the sample file!

I was able to reproduce and identify the issue. The issue is that you have an annotation with invalid custom data from the XFDF:

<trn-custom-data xmlns=“http://ns.adobe.com/xfdf/” bytes="{}}"/>

There is one more } than expected which causes the JSON to be misread. I am not sure how this file was generated but correcting that should resolve the issue.
