  • I can´t download this, tell me that I don´t have credentials

  • when I try to download it I get the following error:


    {"resource":"\/suite\/rest\/a\/content\/latest\/isBCLGOdlMUpdGVqW3KCvlJ3bZ6d_hLmtPbXFIlLc4DByT0PqjU_6GpmS8W\/o","error":"APNX-1-4187-000","message":"Authentication failed. Please check your credentials and try again.","title":"An Error Has Occurred"}
     

  • We are having serious Memory leak / Heap memory Overshoot issues which are causing server crash incidents. We have used PDF to image and image to PDF plugins to cater for one of the client requirements. 

    The same is happening when the plugin is being executed for more than 10 concurrent iterations. Below are the comments from the Appian support team who have identified the problem with the plugin. Could you please check below and resolve ASAP and let me know if you need anything from logs standpoint.

    Hi Team,
     
    The application server restarted on. I have investigated the leak suspects. The application server restarted due to the pdf tools plugin. Here is the thread that is responsible for the app server restart.

  • Hi,

    I am having an issue with parsing data to combo field in pdf. How do I parse data to a combo field. 

    Thanks

  • Hello, we use the function getpdfmetadata in our process. Unfortunately not all possible metadata ware shown (Keywords).
    Is there a way to add this by own or you in the app?

    Thanks and happy day!

  • in reply to Raj

    Hi Raj,

    We are in exactly the same situation. We are in need of this plugin, but with a version 1 reference for the PdfField cdt.

    Did you manage to resolve this yet? And if so, how?

    can you perhaps share a version of the plugin that references the ^1 of PdfField?

    Thank you

  • v2.2.13 Release Notes
    • Bugfix within the getpdfbookmark function

  •  are there recommended doc size limits for some of the conversion smart services? we've seen major degradation / heap consumption with the Convert PDF to Image smart service with sizes larger than a couple hundred KBs.

  • v2.2.12 Release Notes
    • Updated getbookmarks to return the page number associated with each bookmark (0-indexed)

  • Hello, we are getting an error while trying to merge some pdf pages. This error does not occur all the time, just sometimes. I attach the error message

    "The activity class com.appiancorp.ps.pdftools.MergePDFOptimize cannot be loaded."
    Thanks!
