带有 PATCH 方法的 GetX 不起作用（Flutter）

Question

I'm building a function to change passwords for users. The api used to change the user password is called via the PATCH method. I tested the api using Postman and it worked fine. The problem comes when I use the GetX library and call the api through it. I checked and found that the backend is not receiving the request. Where does the problem happen? Here is my code:

ElevatedButton(
              onPressed: () {
                if (_key.currentState!.validate()) {
                  authController.changePassword(newPasswordEditingController.text).then((status) {
                    if (status.isSuccess) {
                      Navigator.pushNamedAndRemoveUntil(context,
                          doneResetPasswordScreenRoute, (route) => false);
                    } else {
                      // showCustomSnackBar("Error!");
                    }
                  });
                }
              },
              child: const Text("Change password"),
            ),

Method change password in AuthController:

Future<ResponseModel> changePassword(String newPassword) async {
      Response response = await authRepo.changePassword(getCurrentPassword(), newPassword);
      late ResponseModel responseModel;
      if (response.statusCode == 200) {
        authRepo.saveUserToken(response.body["token"]);
        authRepo.saveNewPassword(newPassword);
        responseModel = ResponseModel(true, response.body["token"]);
      } else {
        responseModel = ResponseModel(false, response.statusText!);
      }
      update();
      return responseModel;
    }

AuthRepo:

Future<Response> changePassword(String currentPassword, String newPassword) async {
    return await apiClient.patchData(AppConstants.CHANGE_PASSWORD_URI, {"passwordCurrent": currentPassword, "password": newPassword, "passwordConfirm": newPassword});
  }

ApiClient:

Future<Response> patchData(String uri, dynamic body) async {
    try {
      Response response = await patch(uri, body, headers: _mainHeaders);
      return response;
    } catch (e) {
      return Response(statusCode: 1, statusText: e.toString());
    }
  }

patch in ApiClient using GetX library. I checked in browser and it is not working.

Api working with Postman
