Solution

The above error usually happens due to a misconfiguration in the database URL found in the system.yaml. A common issue is using the name PostgreSQL instead of Postgres in the URL. It should normally look like the following.

shared
  database:
    type: postgresql
    driver: org.postgresql.Driver
    url: postgres://<database_host>:<:port>/xray?sslmode=disable
    username: xray
    password: xray
