I am getting an Exception while trying to map the JSON to an object with Jackson.

com.fasterxml.jackson.databind.exc.MismatchedInputException: No content to map due to end-of-input
 at [Source: (org.apache.catalina.connector.CoyoteInputStream); line: 1, column: 0]
	at com.fasterxml.jackson.databind.exc.MismatchedInputException.from(MismatchedInputException.java:59) ~[jackson-databind-2.11.0.jar:2.11.0]

What is the problem? I will put the code snippets in thread

I guess inputstream is already consumed

There is another filter for getting values more than once.
