Hi,

according to the documentation you should be able to call `pdf.reserveobj("annot")`, but doing so results in the error "pdf.reserveobj() optional string must be "annot"". The problem is that a null pointer and not the argument is compared to "annot". According to the website, you are not ready for contributions yet, but I still attached a patch.

Thank you for the report --- can you give a mwe ? I will fix asap.

The mwe would be \directlua{tex.print(pdf.reserveobj("annot"))} \end
