Can you please first analyse your code, in which cases you are adding same key again in the collection and check given stack trace?

Hello,

Thanks for your feedback.
We did analysis based on the stack trace you provided, but we still didn't find the accurate reason of your issue. Maybe your PDF document contains special element or structures. I’m afraid it is hard to provide an accurate solution without your PDF document. Don’t worry, we promise to keep your document confidential and won’t use it for any other purpose, you also can remove the confidential data of your document, just make sure the modified file can reproduce your issue, and then send it to us via email ([email protected]). Thanks in advance.

Sincerely,
Lisa
