How to Handle Error :- type mismatch cannot convert from mediatype to string

I am getting error while making project: type mismatch cannot convert from mediatype to string

There are following steps to solve the error and Exception code:

This is the problem while you are using JAX-RS and Jersey API. you'll be doing same like below:
check following import in your code as below:
org.springframework.http.MediaType;
If you are using above import then please don't use it and not should be this import in your project.

I have replaced it with the following import and feel free to share with you:
import javax.ws.rs.core.MediaType;
