Stash - retrieving Matrix field data

Question

I'm new to Stash and I'm trying to get the data from a Matrix field. The field has two columns, image and video, and there can be more than one matrix row.

I've used the example from the Stash documentation but it's still not working for me. I am getting the non-matrix data fine but not the Matrix items. Can anyone spot what I'm missing?

Thanks.

{if segment_2_category_id}
            {exp:stash:set_list name="news_list" parse_tags="yes" parse_depth="2"}
                {exp:channel:entries channel="news" status="open|featured" orderby="date" sort="desc" limit="10" category="{segment_2_category_id}"}
                    {stash:item_title}{title}{/stash:item_title}
                    {stash:item_url}{url_title}{/stash:item_url}
                    {stash:item_date}{entry_date format="%F %d, %Y "}{/stash:item_date}
                    {stash:item_copy}{news_content}{/stash:item_copy}

                    {exp:stash:set_list:nested name="item_media" context="{entry_id}" parse_tags="yes"}
                        {news_videos_images}

You're trying to use {item_entry_id} for the context parameter when outputting your item_media list, but it doesn't look like it was set? Try adding:

{stash:item_entry_id}{entry_id}{/stash:item_entry_id}

to news_list when you're setting it.
