title: Exception propagation in spring Boot - microservice
body: <p>How to propagate exceptions from one microservice to another in the spring Boot application.</p>
  <p>Ex: when we make a get rest call then we would expect some valid response. Let's say we are expecting a response of type Long. But if there is An exception thrown from the other microservice then how it should be caught and handled in calling the microservice?</p>
  <p>Currently, we are getting a deserialization issue in the token objects.</p>
