DocAssurance Service for encrypting PDF

[Ashar97]

Hello team,

I am trying to utilize the DocAssuranceService to encrypt PDFs. I have created a class using the Sample 1 under the Securing Documents section here:
https://experienceleague.adobe.com/docs/experience-manager-64/forms/use-document-services/aem-docume...

Additionally, I have a servlet identical to the below link, which calls the above class in order to retrieve a certified PDF.

https://experienceleague.adobe.com/docs/experience-manager-learn/forms/creating-your-first-osgi-bund...

I have put a snippet of the class I have created to use the DocAssurance.

public class PassEncryptCertifyExtend {

 @reference
 private DocAssuranceService docAssuranceService;
 
 @reference
    private SlingRepository slingRepository;
 
 @reference
    private ResourceResolverFactory jcrResourceResolverFactory ;

 /**
  * 
  * @Param inputFile - path to the pdf document stored at disk 
  * @Param outputFile - path to the pdf document where the output needs to be stored
  * @throws Exception 
  */
    Document outDoc;
    Logger logger = Logger.getLogger("classname");

 public Document SecureDocument(Document inDoc) throws Exception{

    try {

        

            logger.info("***** CALLING ENCRYPTION OPTIONS *****");
            outDoc = null;
            outDoc = docAssuranceService.secureDocument(inDoc, getPassEncryptionOptions(), null, null, null);
            logger.info("***** EXITING ENCRYPTION OPTIONS *****");
    } catch(Exception e) {
        logger.error(e);
    }
return outDoc;
}

 
outDoc = docAssuranceService.secureDocument(inDoc, getPassEncryptionOptions(), null, null, null);

This line is providing a nullpointer exception when run. I can verify that the inDoc being passed is without any issues. In addition, thegetPassEncryptionOptions() method is being run successfully. I have tried various options such as just passing inDoc with other parameters as null, passing in with all other parameters, yet all variations return a nullPointer exception. The logger indicating the exit of the docAssuranceService.secureDocument does not run and the code returns back to the servlet. I was wondering if I could receive any guidance in this regard.

Error:

hmmm

one last option - can you create your own developingWithServiceUser bundle and use it. The entire code is listed here

Hello,

Thanks for your comment. I had also tried this but it uses the same import which is providing the "import cannot be resolved" errors. The example code similarly uses the 

com.mergeandfuse.getserviceuserresolver.GetResolver

This uses the GetResolver which comes from the zip file attachment from Step 1 in that link (the zip file is the same DevelopingWithServiceUser bundle.
