Server Connect Connection will not save (resulting in error connecting when loading site)

======== TEMPLATE BUG FORM ========

Wappler Version : 3.3.1
Operating System : Mac
Project: NodeJS, Docker, MySql

Expected behavior

I enter Direct Database Connection credentials (for wappler)
I enter Server Connect Connection credentials - and hit save - I expect the credentials to store so that the live site can then connect to the DB.

Actual behavior

What actually happens?

When I hit save, the window closes. When I open up the Server Connect Connection again - all credentials have disappeared.
Direct Database Connection credentials save and I can connect via Wappler fine.

If it adds any context:
I have a staging project (project1) in Docker, with the Docker MySql DB.
I am connecting this second project (project2) to the Docker MySql DB from project 1. This works A Ok with the Direct Database Connection - but when I load the site (hosted on AWS) - the site can’t connect or load data from the DB.

The error I receive in dev tools is:

1. message: “getaddrinfo ENOTFOUND db”
