I keep getting this error : Object reference not set to an instance of an object.
When trying to merge 2 pptx documents.
I’ve enabled dbugging (in the config) with hope to get more info about the error, but not really …..."FileInfo": { "FilePath": "slides/three-slides.pptx" }},{ "FileInfo":..."FilePath": "slides/test.pptx" }} ], "OutputPath": "slides/join.pptx"}"...
