Help required after install of 3.11 on pi, login with admin admin not working

following the guide https://www.traccar.org/forums/topic/installing-traccar-server-on-raspberry-pi-rasperian/
i have setup traccar using mariadb, and can see the default user present.

MariaDB [traccar]> select * from users;

MariaDB [traccar]>

nothing in logs that i can see

However when i try and login with admin admin i get a 500 server error

What is the full API response?

Didnt think about looking at that, seems to be having troubles finding the page but is oddly displaying the login??

:8082/api/session?_dc=1606252736890:1 Failed to load resource: the server responded with a status of 404 (Not Found)

1. Error 404 has absolutely nothing to do with your problem. It's expected.
2. Still waiting for details on the API response.

Other than the api output from developer console on browser I don't know what you mean by api response?

There should be a network tab in your browser with details about each network request (full request and response).

Ah okay sorry, here is the session .

So, where is the response body?

Have you checked wrapper log for errors?

Btw why are you using such an ancient version of Traccar?

Only reason was that the guide used that version as it was written 4 years ago. I didn't want to follow same instructions with newer version encase there was any issues. More than happy to use a newer version if there is a guide for raspberry pi installs.
As in teh java wrapper log, or is the name for another traccar log file? If the latter all i see in logs is tracker-server.log

Doesn't raspberry use a standard Linux os?

Its running Raspbian, from my understanding the PI i have has a 64 bit CPU but Raspbian is 32bit. I read on some forums that people had uncovered issues with running the standard linux installer with 32 bit os? Thus i opted to follow the manual install
