I have been working on Microservices learning path. Trying to call address service from employee service using Open feign in eureka client program, but I'm encountering this error message:

Request processing failed: feign.FeignException: \[302\] during \[GET\] to \[http://address-service/address-app/api/address/1\] \[AddressClient#getAddressByEmployeeId(Integer)\]: \[\[{"addressId":1,"addressLine1":"addressline 1","addressLine2":"addressLine2","cityName":"city","employeeId":1,"stateName":"state","zipCode":"021547"},{"addressId":3,"addressLine1":"addressline1","addressLine2":"addressLine2","cityName":"city","employeeId":1,"stateName":"state","zipCode":"236525"}\]\]\] with root cause

feign.FeignException: \[302\] during \[GET\] to \[http://address-service/address-app/api/address/1\] \[AddressClient#getAddressByEmployeeId(Integer)\]: \[\[{"addressId":1,"addressLine1":"addressline1","addressLine2":"addressline2","cityName":"city","employeeId":1,"stateName":"state","zipCode":"021547"},{"addressId":3,"addressLine1":"addreessLine1","addressLine2":"addressLine2","cityName":"city","employeeId":1,"stateName":"state","zipCode":"236525"}\]\]

But in separate, API calls are working fine.

Please find the some code snippets.

I request your expertise on fixing the issue.
