Exception: Caught unexpected exception during parsing caused by exception: Error while parsing object : 3 0 caused by exception: Object number 1437 should be object stream, but in fact it is null

[HenningRoth]

We are receving NullPointer Exceptions on some PDF Documents.
Unfortunately currently I cannot share a PDF file to reproduce the problem as the files may contain sensitive data.
But the possibility of sharing a PDF is under evaluation by data owner.

Using the actual cli (Release 1.26.2) I get the following messages (receiving the same exception uisng the lib in our application)

c:\users\v081039\Downloads\Gesundheitsfragen.pdf 00:00:00.084 Exception: Caught unexpected exception during parsing caused by exception: Error while parsing object : 3 0 caused by exception: Object number 1437 should be object stream, but in fact it is null 00:00:00.084 1 0 0 00:00:00.133

We got the allowance to share a sample PDF.

Message from cli Version 1.26.2:
