RuntimeError: [json.exception.type_error.302] type must be number, but is object

### Bug
The error happens very rarely, with certain pdf files. Here is an example of such a file - [Marseille.pdf](https://github.com/user-attachments/files/19228200/Marseille.pdf). And actually I have already encountered a similar problem, but in pypdf, and it was solved, so I leave a [link to this issue](https://github.com/py-pdf/pypdf/issues/3153). [Resolved here](https://github.com/py-pdf/pypdf/pull/3158). It would be ideal if you could also ignore such errors, thanks in advance.
