  • Hi

    Previously working "Convert Image to PDF" smart service fails after plugin upgrade to v2.4.0 on 22.1 cloud environment.

    Using the "Convert Image to PDF" smart service to convert a tif to pdf.

    Delete plugin and re-added. Same error occurs.

    Process model fails with an error of "Convert Image to PDF   An error occurred in executing an Activity Class."

    The logs show the following:-

    Having the same issue, had any luck with this in the last couple of days?

  • Hello,

    I am trying to convert a PDF document to image through the relative node "Convert PDF to Image", but there is an error during Activity Class execution. The details report the following:

    bundleName for SmartServiceException, builder.smartServiceClass=class com.appiancorp.ps.pdftools.AbstractPDFDocumentGeneration 

    I have populated the fields for inputs and outputs as follows:

    Inputs:

    • Document: pv!document (type Document)
    • Save In Folder: pointer constant (type Folder)
    • Image Format: JPG (type Text)
    • DPI Resolution: left blank (not mandatory field)

    Outputs:

    • Images Created: docAsImage (Type Document, Multiple)

    Any help appreciated.

    Best regards.

  • Release Notes - v2.4.0
    • Added ability to configure resolution of files outputted from Image to PDF smart service
  • v2.3.3 Release Notes
    • Security Updates

  • in reply to davidl0016

    When a new version of the plugin contains a new version of a CDT, the previous version needs to be deleted before a new one is deployed. Please delete PdfBookmark and redeploy the plugin.

  • Hello, i've just tried to upgrade to the version 2.3.2 and i've got this message :

If you intend to change the structure of this data type you must first delete the data type from the system and deploy this plug-in again.

If you did not intend to change the structure of this data type, this message can be safely ignored as it is a false positive in the structure comparison mechanism.
