Problem with {} in map regex matching

Server NGINX
1

To my surprise, apparently doing a match with {} like in:

map $args $has_tr0_arg {
default 0;

~“tr%5B0%5D%3D=[1-9][[:digit:]]{3}-[[:digit:]]{2}-[[:digit:]]{2}T[[:digit:]]{2}%2F[1-9][[:digit:]]{3}-[[:digit:]]{2}-[[:digit:]]{2}T[[:digit:]]{2}%26”
1;

~"%26tr%5B0%5D%3D=[1-9][[:digit:]]{3}-[[:digit:]]{2}-[[:digit:]]{2}T[[:digit:]]{2}%2F[1-9][[:digit:]]{3}-[[:digit:]]{2}-[[:digit:]]{2}T[[:digit:]]{2}"
1;
}

Doesn’t work.

Which is bit surprising knowing that location regex matching works with
{},
of course you have to quote it, like I do above.

This is what I get from nginx -t:

nginx: [emerg] unexpected “{” in /etc/nginx/nginx.conf

Is this expected behavior or I’m doing something wrong here?

Thanks,

Leading ‘~’ is outside quotes, which results in your regular
expression being interpreted as non-quoted string. Use something
like this instead:

map ... {
    "~(foo){3}" 1;
}
