Connecting to Athena gives a NullPointerException with a null message when not filling up the region section

[paoliniluis]

Describe the bug

If you don't fill the region, it will throw an error immediately with a null pointer exception and a null value

To Reproduce

1. set up an Athena and then try to connect Metabase to it (without filling up the region section)
2. see the error

Expected behavior

It should show the error, and also we should respect the defaults
