I have found a couple of issues on webpage https://mariadb.com/kb/en/library/connect-json-table-type/

Section: Alternate Table Arrangement
[
[56, "Coucou", 500.00],
[[2,0,1,4], "Hello World", 2.0316],
["1784", "John Doo", 32.4500],
[1914, ["Nabucho","donosor"], 5.12],
[7, "sept", [0.77,1.22,2.01]],
[8, "huit", 13.0],
]

insert into xjson values(25, 'Breakfast', 1.414);
Returns: SQL Error (1296): Got error 174 'Unexpected ',]' near ],' from CONNECT

Solution: Remove comma after the last JSON item [8, "huit", 13.0]

Section: CRUD operations on JSON tables
CREATE TABLE jauthor (
FIRSTNAME CHAR(64),
LASTNAME CHAR(64))
ENGINE=CONNECT table_type= JSON File_name='biblio3.json' option_list='Object=2.AUTHOR';

select * from jauthor;
Returns: SQL Error (1296): Got error 174 'Cannot find array value 2' from CONNECT

Solution: Either option_list='Object=1.AUTHOR' or option_list='Object=2.AUTHOR, Base=1'
