I think NodeType you mentioned is dam:AssetContent which means its not
metadata. Generally this node contains only few fields like name,
parentPath, processed etc. You may be need to enable the launcher on
your custom Metadata - In that case few configurations needs to be
modified:NodeType - nt:unstructuredPath -
/content/dam/(/.*/)jcr:content/metadata (something like this)Also,
exclude list may include -
jcr:lastModified,dc:modified,dc:format,jcr:lastModifiedBy,imageMap,event-user-data:changedB...
