App returns "Internal Server Error"

Hi, I am attempting to install on a Synology box running “Container Manger” (I have a lamp stack, Portainer etc. all running just fine.
The containers all install and run without errors.
I have changed the following items
Port is 8081:8080
I have tried a degraded version image: frappe/erpnext:v13.51.6
Both return the exact same error
I would apreciate any pointers

Kind regards
