 The error is

 {{{
 Warning: vsprintf(): Too few arguments in wp-includes/wp-db.php on line
 1397
 }}}

 I found the root cause that if the encoded slug contains the {{{%f}}} or
 {{{%[0-9]f}}}. it will be converted to capital F (wp-db.php:1359) and will
 not be properly escaped (wp-db.php:1361)

 I found a ticket here https://core.trac.wordpress.org/ticket/49140 but it
 has been closed.
