Hi Frédéric,
Thank you for contacting Syncfusion support.
We have checked by exporting the freeText annotation. But we were unable to replicate the reported issue. We have shared the sample in which we tried to replicate this issue. We suspect that the reported issue is due to the different packages referred to the Client (React) and Server (Asp.Net Core). So, we suggest you use the same version in both client and server to get the issue resolved.
Screenshot of Client(React) version:

Could you please try the sample and let us know whether you are facing the same issue? And kindly share the modified sample in which you are facing this issue. It will be helpful for us to investigate further and provide the details at the earliest.

Hi Frédéric,
Thank you for the JSON file. We have checked the provided JSON file. But we are getting the issue as “Object reference not set to an instance of the object exception while downloading the file after importing the provided JSON file”. We will analyze further and provide the details on September 29, 2021.
Screenshot of the error which we are getting in our end:
In the meantime, could you please confirm us whether you are facing the same issue “Object Reference not set to an instance of the object” while downloading the document with the provided JSON data. Please confirm whether you have exported the provided JSON file from the Syncfusion PDF Viewer or any other control? And please ensure to use the same version (client & server) for performing the importing and exporting functions of JSON data. And please confirm whether you have any modification done manually on the exported JSON file or please share the code snippet of export annotation and import annotation which are using on your end. This will be helpful to investigate further and assist you better.
Regards,
Dhivya.
