micronaut runs with the DB on dev/test but not with the build image - postgresql

Question

I'm trying to use postgres on a micronaut project. When running locally, or by executing the tests, everything works correctly. But when I try to generate a docker image and run it I got the following error:
Caused by: org.hibernate.HibernateException: HR000048: Could not determine Dialect from JDBC driver metadata (specify a connection URI with scheme 'postgresql:', 'mysql:', 'cockroachdb', or 'db2:')
According to the official documentation:
When you move to production, you will need to configure the properties
injected by Test Resources to point at your real production database.
This can be done via environment variables like so:
I should set some application items described onthe JDBC section of the guide
So here is my application.yaml:
micronaut:
application:
name: micronaut-guide
netty:
default:
allocator:
max-order: 3
#tag::jpa[]
jpa:
default:
entity-scan:
packages:
- 'example.micronaut.domain'
properties:
hibernate:
show-sql: true
hbm2ddl:
auto: update
connection:
db-type: postgres
reactive: true
#end::jpa[]
datasources:
default:
driverClassName: org.postgresql.Driver
db-type: postgresql
schema-generate: CREATE_DROP
dialect: POSTGRES
jpa.default.properties.hibernate.hbm2ddl.auto: update
Plus, I've tried to pass some environment variable when running it:
docker run micronaut-postgres -p 8080:8080 --rm -e DATASOURCES_DEFAULT_URL=$DATASOURCES_DEFAULT_URL -e DATASOURCES_DEFAULT_USERNAME=$DATASOURCES_DEFAULT_USERNAME -e DATASOURCES_DEFAULT_PASSWORD=$DATASOURCES_DEFAULT_PASSWORD
◼ ~/Code/Personal/micronaut-postgres $ echo $DATASOURCES_DEFAULT_URL 130
jdbc:postgresql://localhost:3306/db
to be sure there are all the pieces here is my build.gradle:
plugins {
id("org.jetbrains.kotlin.jvm") version "1.6.21"

}
Another more standard way to replicate the problem
I got into the same problem with the official example on the micronaut website available here.
I can generate the docker image, run it and the same problem arises:
