NullReferenceException in Spire.Pdf.PdfPageBase.FindAllText

[bbrodnik]

When trying to get text from certain document, I always get System.NullReferenceException with following stack info:

System.NullReferenceException: Object reference not set to an instance of an object.

at sprᮜ..ctor(PdfPageBase A_0)
at sprᦿ.ᜀ(PdfPageBase A_0)
at Spire.Pdf.PdfPageBase.FindAllText()

Document doesn't seem to be corupted (attached) since Adobe reader opens it correctly with no errors.

I also have other documents (one more attached) with same error, if it helps for testing.

System.NullReferenceException is also returned with other API calls, for example:

at sprᤵ.ᜁ(Int32 A_0)
at Spire.Pdf.Widget.PdfPageCollection.ᜀ(Int32 A_0)
at Spire.Pdf.Widget.PdfPageCollection.get_Item(Int32 index)
at Spire.Pdf.PdfDocumentBase.ᜀ(Int32 A_0, Int32 A_1, Int32 A_2)
at Spire.Pdf.PdfDocument.SaveAsImage(Int32 pageIndex, Int32 dpiX, Int32 dpiY)
