Error when trying to export to Powerpoint or PDF

[Anonymous]

Hi all,

I get this error (see image below) if I want to export my report to Powerpoint or PDF. I created the report myself, published it, and if I want to export it, this error pops up. First it did work, so I don't know what's the reason why it doesn't at the moment. And the error details don't give me extra information on how to solve it. Already deactivated all relationships in the model, checked all custom columns, no blank pages in the report, no errors in visuals or query's.

Can someone help me?
