"No such connection with name \"default\" exists" or "Connection Already Exists"

[alfredopatnella]

Hi. Thanks for a wonderful library.

I am having trouble with LAMBDA implementation as if I create the connection it works fine the first time, but the next time, since the lambda is already running it yells about the connection already existing.

Is there a way to determine if the connection is already established like in typeORM with getConnectionManager().connections.find('default'); or something similar?

Or is there another smart way to handle this?

There is getConnection() for retrieving the default connection. It throws if the connection does not exist yet.

For named connections, you would have to retrieve the ConnectionManager from the Container and then do .get("something").

const connectionManager = Container.get(ConnectionManager)

try {
  return connectionManager.get(name)
} catch(e) {
  return createConnection({ ... });
}

I see the No such connection with name error post moving to Node v18. Is there some sort of compatibility issue?
