Howto pass the uid of a node to a view inside a dynamic display suite field?
You are incorrectly setting the 'Argument input' for the Content Pane. It needs to be Node -&gt; Author

Then you need to make sure that you pass the correct argument to it from the Dynamic Field in Display settings for the node. Make sure that you select 'View Panes' and not 'Views'. When you do it will show you the View pane view that you created, and when you select that it will present you with a select list titled: 'Content: Author uid', from which you select the only choice available, which is 'Node being viewed'.

I also do not think that setting the 'When the filter value is not available' in views will have any effect at all. This content pane display is only used for the dynamic field which will always get an argument.
