pulumi: S3 Bucket(s) in broken state

Today I started receiving the error: preparing urn:pulumi:dev::pulumi-test::aws:s3/bucket:Bucket::web-assets-bucket's old property state: expected string or JSON map; got <nil>

This initially happened on a large existing project, but I am able to quickly replicate the issue by attempting to import one of the problem buckets in a fresh AWS+Typescript project slightly modified from the template.

Full contents of my simple project index.ts:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
import * as awsx from "@pulumi/awsx";

// Create an AWS resource (S3 Bucket)
// const bucket = new aws.s3.Bucket("my-bucket");

// const bucket = aws.s3.Bucket.get('web-assets-bucket','irisvr-dev-web-assets')

const bucket = new aws.s3.Bucket('web-assets-bucket', {
  bucket: 'irisvr-dev-web-assets'
}, {
  import:'irisvr-dev-web-assets'
})

// Export the name of the bucket
export const bucketName = bucket.id;

I can successfully ‘get’ the bucket by commenting that section and commenting the ‘new’, but importing immediately throws the error at the top of this issue.
