JI must admit, my first reaction was excitement because this is the first time that check I added has come in useful. Anyway, do you mind if I ask why you are using a rewrite like that one?
JBy design, that rewrite would match any path, which is why I'm curious to know more about why one like that is needed
JThe thing is, that rewrite is designed to rewrite
/* to /api/avatar/*. When it doesn't find a file that matches at /api/avatar/*, it hits the rewrite again, according to the rules in the build output config that we respect
