Hi I've looked over the code and am getting an issue with PYPDF2 data when the set with copy warning is being raised, would it be possible for warning code to be inside a try look so raising a warning doesn't break a process ?

Feature Description

Nest Warnings in a try statement to avoid the raising of one causing an error

Alternative Solutions

Having a default warning raised where the warning cant be produced in full

Additional Context

No response

hi @pettzilla1 - could you provide a reproducible example please?

Hi @MarcoGorelli unfortunately I cant send over an example,

It seems to be an issue when the warning tries to asses where the objects data has originally come from it recursively go's back and tries to access something it shouldn't be ,

needless to say however the warnings should ether be inside a try loop or something else to avoid a system falling over due to a warning trying to be raised and failing , especially if it is part of an update or process change

no worries, if/when you can come up with a reproducible example we can take a look, at the moment there's just nothing to go off of
