Return value of CodeIgniter\Database\BaseConnection::getConnectStart() must be of the type float, null returned

[Martin-4Spaces]

This error occurs if I connect to a database group but never use it.

Ex.

$routes->get('issue', function() {
    $db = Database::connect('default');
    echo 'Nah, I dont need the connection anyway';
});

connectTime in BaseConnection is set when the first query is run. But Database::formatTimelineData will always call getConnectStart.

I'm not able to reproduce this error using either develop branch or RC.1

Me neither, tested with default and an additional DB connection with the debug toolbar collector on.

[Martin-4Spaces]

Me neither. Ty!

Aha!
I finally reproduced this issue using develop branch and RC.3.

If you connect to the database in a pre_system event, then toolbar will initialise with 1 database connection. And fail if the connection is never used.

app/Config/Events.php:

Events::on('pre_system', function() {
	Database::connect();
});
