Feign Exception UnsupportedMediaType during POST call to Jira rest endpoint

[Bradley Willis]

I have been trying to programmatically create version for a Jira project using Spring Cloud Feign.

I am following https://developer.atlassian.com/cloud/jira/platform/rest/v2/api-group-project-versions/#api-rest-api-2-version-post

I am able to successfully execute the POST call via Postman, with request payload like :

  {
        "name": "ABC 2022.01.000",
        "archived": false,
        "released": true,
        "projectId": 30500
    }

However, when I try to create it through the feign client I get below exception :

Caused by: feign.FeignException$UnsupportedMediaType: [415] during [POST] to [https://jira.abc.com/rest/api/2/version] [JiraFeignClient#createVersion(VersionDTO)]: []

My feign client method:

@PostMapping(value = "/rest/api/2/version")
ResponseEntity<Object> createVersion(@RequestBody VersionDTO versionDTO);

VersionDTO.java :

@NoArgsConstructor
@AllArgsConstructor
@Builder
@ToString
@Getter
@Setter
public class VersionDTO {

    private String name;

    private Boolean archived;

    private Boolean released;
    
    private Long projectId;
}

Not sure what's wrong with my DTO. Any guidance is appreciated.
