Getting Error in calling com.adobe.icc.services.api.LetterInstanceService from AEM Workflow process step

I am trying to get all Correspondence Letters from a workflow process step (AEM Workflow on OSGi ) , I am using the below API's but getting error related to {Code}-LCC-REP-JCR-001, {Message}-Error in getting a JCR session.

@Reference

private com.adobe.icc.services.api.LetterInstanceService letterInstanceService;

@Reference

private com.adobe.icc.services.api.LetterService letterService;

public void execute(WorkItem item, WorkflowSession session, MetaDataMap args) throws WorkflowException  {

...

List<LetterInstanceVO> letterInstances = letterInstanceService.getAllLetterInstances(null);

// List<Letter> letters = letterService.getAllLetters(query);

...

}

Error :

com.adobe.livecycle.content.query.exception.QueryException: QueryException: {Code}-LCC-REP-JCR-001, {Message}-RepositoryException: {Code}-LCC-REP-JCR-001, {Message}-Error in getting a JCR session

I have tried with both LetterInstanceService  and LetterService  with both query parameter and null. Please suggest whether we can use this API or not. I am using AEM 6.3 + cfp + forms addon package

    This is the sample code snippet from my jsp page which is in production at some of our customers

    Statement statement = new Statement();

    statement.setAttributeName("name");

    statement.setAttributeValue("Ba");

    statement.setOperator(Statement.Operator.STARTS_WITH);

    Query query = new Query();

    List<Statement> statements = new ArrayList<Statement>();

    statements.add(statement);

    query.setStatements(statements);

    LetterService letterService = sling.getService(LetterService.class);

    List<Letter> letterList =  letterService.getAllLetters(query);

        Yes bundle is in active state.

        Adobe Asset Composer Building Block Bundle (com.adobe.livecycle.acm)

        I am referring the below documentation

          Also - i am assuming you are following some sort of online AEM Docs. Can you please point the community to that doc.

            Letter Service seems to be an add on. Do you have the OSGi bundle that exposes that Service in an Active State.
