npm start error (TypeError: Cannot read properties of undefined (reading 'driver'))

I have a fresh installation of the update server installed on my linux system. I have installed postgres with the documentation. On Startup i get the following error:

error: A hook (`orm`) failed to load!
error: Failed to lift app: Exception: `getConnection` failed ("failed").  Could not acquire a connection to the database using the specified manager.

so i have copied the local.js and filled in all fields. The interesting is that he tries to connect to “hostname: ‘electron_release_server_user’” but this is the username and not the host. The local.js is loaded and all hosts are set to “localhost”. We have checked this some times now. So he can’t resolve that name.

  datastores: {
    postgresql: {
      adapter: 'sails-postgresql',
      database: 'electron_release_server',
      host: 'localhost',
      user: 'electron_release_server_user',
      password: 'xxxxx',
      port: 5432
    }
  },

  session: {
    // Recommended: 63 random alpha-numeric characters for secret
    // Generate using: https://www.grc.com/passwords.htm
    secret: 'xxxxxx',
    database: 'electron_release_server_sessions',
    host: 'localhost',
    user: 'electron_release_server_user',
    password: 'xxxxx',
    port: 5432
  },

In the file were the error occurs i have printed the variable and driver is set. To tests if it’s working when node can resolve the IP i have added the username to the /etc/hosts. Then he can find the driver but not the connection.

/var/www/xxxx/node_modules/waterline/lib/waterline/utils/system/validate-datastore-connectivity.js:22
console.log(adapterDSEntry.driver.getConnection);
                                  ^
TypeError: Cannot read properties of undefined (reading 'getConnection')

Any ideas on that?

We have some pies running as webserver for some really small updates and sites. And i thought i install it on that system, too. Next time when i am at the office i will test the system on a normal Ubuntu. Thanks for your great help 😃
