Can you see, which part is failing? Is it "you set the body, but it is
not what you expect"; or something else?

If you "tcpdump" the port-3000 traffic, do you see anything interesting?

I get:

nginx: [emerg] "proxy_pass" cannot have URI part in location given by
regular expression, or inside named location, or inside "if" statement,
or inside "limit_except" block

(And more failures, after changing that. Generally: there are limited
things that you can do inside an "if" block.)

If you remove that "if", do things work differently for you?

http://nginx.org/r/$request

That is probably not the variable that you want to use.

Maybe some combination of $server_name or $host, and $request_uri,
is more useful?

Reverse the test?

if ($is_a_bot) {
return / rewrite / whatever
}
proxy_pass ...

Good luck with it,
