i think you already have an answer to your question.
please check whether "mysql.innodb_index_stats" really exist as a table.
on mysql, type: show tables
check whether the error of mysql is just trying to trip you up.
if indeed it's true; try creating the said table and run the command that you want and check if you will have an error again.
after creating the table, just run once the command that you want. If you run it more than once, you will end up with an error.
