Use of inputPageName in pxGenerateJWT

I would like to find out more about the use of the inputPageName Parameter in the pxGenerateJWT. We wanted to use the inputPageName to populate custom claims that are dynamic.

I created a page of the Embed-Token-JsonWebToken-Generation class, and populated with a custom claim. However, I kept on getting a runtime NullPointerException.

I am on Pega 8.1.3. Can somebody show me how to set up a proper inputPageName for pxGenerateJWT?

The step 2 of the pxGenerateJWT is similar to this - you should be able to do a private checkout to debug where this NPE is coming from and act accordingly.

jwtGenerationPage = jwtInstancePage.getPage("pyJsonWebTokenGeneration");
if(jwtGenerationPage != null){
  if(contextPageName!=""&&contextPageName!=null){
ClipboardPage contextPage = tools.findPage(contextPageName);
if(contextPage != null){
      ClipboardProperty headersList = jwtGenerationPage.getIfPresent("pyHeaders");
      ClipboardProperty contextheadersList = contextPage.getIfPresent("pyHeaders");
      for (int i = 1; i <= contextheadersList.size(); i++) {
        ClipboardPage customHeaderpage = contextheadersList.getPageValue(i);
        ClipboardPage headerpage = headersList.getPageValue(ClipboardProperty.LIST_APPEND); 
        headerpage.putAll(customHeaderpage );
