Research direction

Start by locating how plugin settings annotations and nargs are parsed, then trace the handling of a List[str] setting. Reproduce the reported failure with --sdm-container-mountpoints /data:/data; done when list-valued settings parse without the reported TypeError and the value is accepted.

Written by the indexing model from the issue text.

Description

Plugin settings type annotated with List[str] and nargs can't be read.
For example, --sdm-container-mountpoints /data:/data fails with TypeError: Type List cannot be instantiated.
