I am getting this Exception while converting pdf to Searchable PDF. This what the code I am applying.

public static String ConvertPDFToSearchable(String inputFilePath, String outputFilePath)
{
Document doc = new Document(inputFilePath);

        try
        {
            //doc.Validate("validation-result-A1A.xml", PdfFormat.PDF_A_1B);
            doc.Convert(CallBackGetHocrWidthDLL);
            doc.Save(outputFilePath);
        }
        catch (Exception ex)
        {
            try
            {
                String TempPath = String.Format("{0}/{1}.tiff", Path.GetTempPath(), DateTime.Now.ToFileTime());
                TiffHelper.PDFToTiffImageOnOCRError(inputFilePath, TempPath);
                ConvertTiffToSearchable(TempPath, outputFilePath);
                File.Delete(TempPath);               

            }
            catch (Exception innerEx)
            {

                LOGMANAGER.LogsManager.Logger.LogProcessInfo(typeof(OcrConverterWithAspose)
                                          , COREDATAMODELS.LogLevel.SubComponent
                                          , nameof(OcrConverterWithAspose)
                                          , nameof(ConvertPDFToSearchable)
                                          , null
                                          , String.Format("Exception Occure.. {0}", innerEx.Message)
                                          , COREDATAMODELS.Stage.End);
            }
          

            LOGMANAGER.LogsManager.Logger.LogProcessInfo(typeof(OcrConverterWithAspose)
                                           , COREDATAMODELS.LogLevel.Component
                                           , nameof(OcrConverterWithAspose)
                                           , nameof(ConvertPDFToSearchable)
                                           , null
                                           , String.Format("Exception Occure.. {0}", ex.Message)
                                           , COREDATAMODELS.Stage.End);             
        }

        return outputFilePath;
    }

Thank you for sharing requested data.

We have worked with the application shared by you but are unable to notice any exception in our environment. It keeps executing smoothly and produces a PDF document fine. We have attached generated file for your kind reference. output.pdf

We have used Aspose.PDF for .NET 19.6, Tesseract 3.3.0 in Windows 10 with .NET Core 2.2.

Thanks for your valuable time. Actually I was handling the Exception, Try Catch was there. So may be that’s why you are not able to reproduce the given exception. I am sharing you the code without Try catch. Can Please look into this.
