Log in Redirect help for Vouch

[rpangrazio]

So I am trying to redirect to a subdirectory of a domain using the vouch auth module from an nginx proxy. This is a the part of my config yml

  login:
    settings:
      routeonlogin: "/"
      allowedcontinueurls: 
         - https://my.domain/.*
      throttleduration: 1s

My nginx vouch block is :

    location = /validate  
    {  
        internal;
        proxy_pass http://simpleauth/api/v1/auth/vouch?continue=https://my.domain$request_uri;
        proxy_pass_request_body off;
        proxy_set_header Content-Length "";
        proxy_set_header X-Original-URI $request_uri;
    }

And here is the request from the simple auth container:

time="2024-05-14T17:57:59Z" level=info msg="1.2.3.4 GET /api/v1/auth/vouch?continue=https://my.domain/status/ 401 112" cid=oB8dPtYZo3yH
time="2024-05-14T17:57:59Z" level=info msg="1.2.3.4 GET / 200 1709" cid=gHolCMv64mHu
time="2024-05-14T17:58:00Z" level=info msg="1.2.3.4 GET /api/v1/account 401 112" cid=6TZgWqL37nts
time="2024-05-14T17:58:08Z" level=info msg="Attempting login for 'user'..." cid=dnGsIQfJZ8eA
time="2024-05-14T17:58:08Z" level=info msg="Login for user 'user' accepted" cid=dnGsIQfJZ8eA
time="2024-05-14T17:58:08Z" level=info msg="1.2.3.4 POST /api/v1/auth/session 200 46" cid=dnGsIQfJZ8eA

I've changed some details to remove IP addresses, domain names, and stuff but have kept them consistent.

Every time it just gets redirected to / of my domain. I've tried all sorts of different patterns in the regex. Including explicitly writing the URL. I have put them in " I have put them in ' and I have left them without. Always redirects to root.
