com.aspose.slides.BaseSlide.equals Error Exception in Code: Parameter Is Not Valid

22.3 version is OK (and it’s been working for a couple of years) but
22.4 calls to com.aspose.slides.BaseSlide.equals
can now throw an exception…

Error Exception in code: Parameter is not valid.

surely a call to com.aspose.slides.BaseSlide.equals(Unknown Source) should never throw an exception?
either the slides are equal or not? I’m hoping you can track the bug without me having to write a small amount a code and a simplified example without copyright issues in :slight_smile:

@JamesDriscoll,
Thank you for contacting support.

This is a public method, maybe that is why it can throw exceptions. Our developers assume that the error occurs while processing an image. Could you please share the presentation file?

not easily - I’ll have to do some testing to see if I can send something that is anonymous. Why would the exception be thrown when processing an image? either slide A is equal to slide B or it isn’t.
This is something that was introduced between 22.3 and 22.4 so I was hoping it would be easy for the developers to find rather than me having to jump though some more hoops (I’ve been using aspose since nov 2020 )
