  • Hello, I am trying to use the "Convert Image to PDF" Smart Service.

    Trying to convert an .SVG file to PDF, an unspecified error occurs. Is this as intended? Are SVG images not supported?

  • 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:-

  • 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)

    Any help appreciated.

    Best regards.
