All the examples on webpage https://mariadb.com/kb/en/library/connect-xml-table-type/ run Ok but after running:

create table xsacol
engine=CONNECT table_type=XML file_name='Xsample.xml'
tabname='BIBLIO' option_list='rownode=BOOK,Level=1' catfunc=col;

The query:

select column_name Name, type_name Type, column_size Size, nullable, xpath from xsacol;

returns the following error:

SQL Error (1030): Got error 174 "Fatal error during initialization of handler" from storage engine CONNECT
