Cross post from #CRH5ENVDX (https://pulumi-community.slack.com/archives/CRH5ENVDX/p1728080444995569) . Essentially having problem with a stack trace from pulumi rpc runtime if I specify any value for aws rds instance object property

performance_insights_kms_key_id

How are you passing

master_args

to Instance?

The object creation is:

master_db = pulumi_aws.rds.Instance(
            resource_name=instance_id,
            args=master_args,
            opts=ro,
        )

This works if I don't specify

performance_insights_kms_key_id

so its does not appear to be code/logic issue. It appears to be something specific about setting that value.
