Thanks so much! Please attach your .platform (zipball) and .platform.app.

@rfay I added them to the description

Shoot, your mariadb looks like this ("db"):

db:
    type: mariadb:10.4
    disk: 2048

whereas the one I was mostly working with was "dbmysql":

dbmysql:
    type: oracle-mysql:8.0
    disk: 2048

I see that postgres also has "db":

db:
  type: "postgresql:13"
  disk: 2048

It seems that in .platform.app the name of the database header is given in the name of the relationship:

relationships:
    database: 'dbmysql:mysql'

Completely useless behavior :(

I see that the key "dbmysql" is the key to what we're going to find in resources. I have no idea what the value "mysql" means. I guess we talked about this and maybe it means the name of the service. Seems that both mysql and mariadb have the value "mysql" and postgres has the value "postgresql".

The righthand side of the : is the "endpoint name", which can be ignored in our case AFAICT

This endpoint name is arbitrarily defined
