Terraform 0.13 requires snapshot_identifier explicitly set to null

[nnsense]

what

• With terraform 0.13 If snapshot_identifier is set to "" then the resource creation will fail ("snapshot_identifier": conflicts with username).
• Apparently it works with >0.14 instead.

why

It seems resource "aws_db_instance" "default" defined into main changed (apparently, an hour ago?) its flexibility in taking arguments. Before (also with 0.13) defining "" was enough to use username and password for the DB. Now, I've got this:

Error: ConflictsWith

No references, and I might even be wrong, I rely on your testing to confirm the issue ;)

@nnsense can you push an empty commit via git commit --allow-empty -m "Trigger GH Action" and then git push. We're having issues with our GH actions not triggering / reporting back status sometimes and the only way to force it is with a new commit.

Once we've got a green build then we'll get this merged. Thanks!
