When requesting the next page, it will not return the actual paging object but rather the root level endpoint object. A good example is the <code>Search</code> endpoint, which contains up to 5 Paging objects. Requesting the next page of the nested <code>Artists</code> paging object will return another <code>Search</code> response, instead of just <code>Artists</code>. You will need to supply a mapper function to the <code>Paginate</code> call, which returns the correct paging object:</p><divclass="mdxCodeBlock_iHAB"><divclass="codeBlockContent_32p_"><buttontype="button"aria-label="Copy code to clipboard"class="copyButton_1BYj">Copy</button><divtabindex="0"class="prism-code language-csharp codeBlock_19pQ"><divclass="codeBlockLines_2n9r"style="color:#bfc7d5;background-color:#292d3e"><divclass="token-line"style="color:#bfc7d5"><spanclass="token plain">var search = await spotify.Search.Item(new SearchRequest(</span></div><divclass="token-line"style="color:#bfc7d5"><spanclass="token plain"> SearchRequest.Types.All, "Jake"</span></div><divclass="token-line"style="color:#bfc7d5"><spanclass="token plain">));</span></div><divclass="token-line"style="color:#bfc7d5"><spanclass="token plain"style="display:inline-block">
