  • Hi,

    I'm using version 2.8.0 of the PDF Tools plugin on Appian version 24.3 and I'm having an issue with the Convert PDF to Image smart service. Sometimes when convering a PDF to an image, the text in the PDF is missing in the image.

    I'm getting this error in the system logs:

    org.apache.pdfbox.contentstream.PDFStreamEngine - Cannot read JBIG2 image: jbig2-imageio is not installed

    This error has happened earlier, on 27th Sep 2024, with an older version of the plugin. After upgrading the plugin to the latest version (2.8.0), the same error is still occuring for some PDFs.

    Has anyone else had the same issue?

  • Hello Team, we have suddenly started have started facing issues with Pdf tools plugin in production environment, we are currently using 
    Convert PDF To Image & Convert Image To PDF modules from the subjected plugin.
    The above-mentioned nodes get failed with error saying, "An error occurred in executing an Activity Class." and an attempt to restart the node sometimes fixed the issue with the instances and sometimes it takes 2 to 3 restart attempts to successfully resume the process and meanwhile it keeps giving the same error.
    We are using latest version of the plugin 2.8.0 currently. any input will be greatly appreciated.

  • Hello,

    Unsure if anyone else is experiencing this issue or has experienced this issue but for few documents, getpdfmetadata() function is throwing error:

    An error occurred while evaluating expression: pdfMetaData:getpdfmetadata(todocument(pv!documentsData['recordType!... (Expression evaluation error at function 'getpdfmetadata': XML handling failure trying to convert value com.appiancorp.ps.pdftools.types.PdfMetadata@77d5bc12 to Appian type PdfMetadata (id=3818))

    there are no similarities between the documents, but its occuring for some documents randomly.

    Any advice is appreciated.
