When struct is put inside a list
 {{schema = pymongoarrow.api.Schema(

Unknown macro: {'_id'}

)}}
 
it raises
 {{> raise ValueError(msg)
E ValueError: Unsupported type identifier <class 'pyarrow.lib.StructType'> for field 0}}
 
As the case for lists in the function _normalize_typeid exists, then it seems that it should be supported, but there is a bug.

Expected behavior:
 {{<Schema

Unknown macro: {'_id'}

>}}
 
See #223 for a fix.

Further problem is setting bson.ObjectId inside the struct inside the list
 {{schema = pymongoarrow.api.Schema(

Unknown macro: {'_id'}

)}}
 
which raises a TypeError:
 {{_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
pyarrow/types.pxi:4711: in pyarrow.lib.struct

pyarrow/types.pxi:3417: in pyarrow.lib.field
???
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

> ???
E TypeError: DataType expected, got <class 'type'>

pyarrow/types.pxi:5066: TypeError}}
 
It is fine in the case of list of only bson.ObjectId:
 {{schema = pymongoarrow.api.Schema(

Unknown macro: {'_id'}

)
->
<Schema

Unknown macro: {'_id'}

>}}
