Hello everyone.

Thank you for taking the time to respond. I noticed an unusual behaviour: when we print in the logger.info, we get an empty text, while the same data is populating in the payload.

 Quite strange behaviour

@kbitra1998 You should be able to get value in logger.info as well, not sure how are you passing parameters to logger. Did you get a chance to print the same variables/parameters using system.out.println(for testing purpose)?

The mistake I have made is logger.info ("AEM" + parameter) it is printing in the logs. However, if I put logger.info("AEM", parameter) it is not printing in the logs.

Check if formdata that you are passing are properly populated in your javascript. You can print that in console and check.

Sharing the code that works for me:

var formData = new FormData($("#formId")[0]);

Make sure in your form you have all your inputs set with name and value, name matching with the request parameter name that you fetch in the servlet.
