I’m trying to use a rewrite in nginx-openresty following a simple example:

location /test 
{
   rewrite_by_lua_block { ngx.req.set_uri("/authgp") } 
}

location /authgp {
    proxy_pass http://authwf.org:9001/realms/gp/protocol/openid-connect/token;
}

When I invoke /test, nginx try to find a file named: [error] 35890#5234410: *1 open() “/opt/ho…/auth instead of forwarding to location /authgp as the example says.

How can I tell nginx-openresty not to try to resolve a file but a location?

Thanks!
Fernando
