Hi anttipekkarinen,System.IO.InvalidDataException function means that a compressed data stream is in a format that is not valid.Reference: https://msdn.microsoft.com/en-us/library/ms241600.aspxBesides, could you please share more details about the special PBIX file, was it compressed?In addition, check to see if the following article would help:http://george.chiramattel.com/blog/2007/09/deflatestream-block-length-does-not-match.htmlRegards
