How to make a redirect to nginx with a sign?

Question

Nginx

Good afternoon, how can I redirect to nginx, at the moment there are two urls with a question mark.
A redirect is needed for pages like
https://yzi4d.ru/shali/endokrinologiya-v-shali/?amp
to redirect to the page
https://yzi4d.ru/shali/endokrinologiya-v-shali/amp/
the presence of the sign confuses? because of which the standard method did not help

Answer 1

if ($request_uri ~ "^([^?]+/)\?([a-z]+)$") {
    return 301 $1$2/;
}
