Morning! I've just joined this Slack group so not sure if this is the right channel...but here goes. I'm trying to apply a major version upgrade to an RDS instance. I've changed

engineVersion

to 14 and tried to run

pulumi preview

, but I get this very strange error:

panic: fatal: An assertion has failed: Expected diff to not require deletion or replacement during Update of <urn redacted>

This worked in another environment, so I'm not sure what is causing this. Anyone seen this before?

Any panic is usually a bug. Can you submit an issue to https://github.com/pulumi/pulumi-aws?
