Neo4j doesn't allow maps as properties (no sub-properties allowed, basically), and though lists are allowed as properties, they cannot be lists of maps (or lists of lists for that matter).
You can either use properties as-is on the node itself like (c1:Config {name:"CiPipelineConfig1", type:"test"}), or if you do need some means of grouping, create an additional connected node (or nodes) to hold the properties according to the grouping needed.
