It seems like there was a bug in auto creating the database connections for targets using the new mysql2 driver. Those were not auto created and had to be entered manually.
it will be fixed in the next Wappler 7 beta.
Just to clarify the workflow, when using a single database service in the same server with multiple projects, then:
- the server connect database connection should have as host the database service name (as it runs locally on the same server) and the default port (3306 for mysql/mariadb)
- the direct connection for Wappler in the database manager should list the server ip as host and the externally defined port (like 9910) in as defined in the database service
