카카오 채널 관계 확인 api시 오류 문의

REST API

문의 시, 사용하시는 개발환경과 디벨로퍼스 앱ID를 알려주세요.
개발환경 SpringBoot 2.7.3 , ID : 925073

현재 카카오 채널 친구 관계 확인 api를 개발하면서 하단과 같은 오류를 계속 확인하고 있습니다.

channel_public_ids 파라미터는 배열 형식의 JsonString을 인코딩하여 전달해야 합니다.
“…?channel_public_ids=” + URLDecoder.Encode("[\"_채널아이디\"]","utf-8")

 String[] channels  = new String[1];

    channels[0] = URLEncoder.encode("채널 id", "UTF-8");

스프링에서 위와 같이 계속 보내고 있는데 요청이 잘 되는건 적고 거의 매번 오류가 나와서 문의드립니다.
형식과 인코딩상 문제가 없는 것 같은데 왜 계속
failed to parse parameter
이 오류가 뜨는 걸까요??

안녕하세요.

작성된 코드를 전부 보여주시겠어요?

        String[] channels  = new String[1];

        channels[0] = URLEncoder.encode("test", "UTF-8");

        KakaoChannelResponseDto kakaoChannelResponseDto = null;
        try{
            kakaoChannelResponseDto = kakaoClient.getKakaoChannelRelationship("Bearer "+accessToken, channels);


@FeignClient(name = "kakaoclient", url = "https://kapi.kakao.com")
public interface KakaoClient {

    @GetMapping(value = "/v1/user/service/terms")
    KakaoTermsResponseDto getKakaoTermsWithHeader(@RequestHeader("Authorization") String authorization);

    @GetMapping(value = "/v2/user/me" , consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
    Map<String, Object> getKakaoUserInfoByToken(@RequestHeader("Authorization") String authorization);

    @GetMapping(value = "/v1/api/talk/channels")
    KakaoChannelResponseDto getKakaoChannelRelationship(@RequestHeader("Authorization")String authorization, @RequestParam(name = "channel_public_ids") String[] channels);
}

Spring OpenFeign을 사용해서 api를 통신하고 있는데 정상적으로 친구 관계 확인이 될 때가 있고 아닐때가 있어서 문의드립니다

OpenFeign으로 통신했을때 로그는 하단과 같아요

channel_public_ids 값은 배열이 아닌 JSON Array 형태의 String 값이 전달되어야 합니다.

ex)

@GetMapping(value = "/v1/api/talk/channels")
    KakaoChannelResponseDto getKakaoChannelRelationship(@RequestHeader("Authorization")String authorization, @RequestParam(name = "channel_public_ids") String channels);

kakaoClient.getKakaoChannelRelationship("Bearer " + ...,  "[\"_test\"]");
