I'm trying to import an existing bucket with:

bucket_sse = aws.s3.Bucket.get(
    resource_name = "dev-file-storage-sse",
    id = "arn:aws:s3:::dev-file-storage-sse"
)

Pulumi complaining about the arn though:

aws:s3:Bucket (dev-file-storage-sse):
    error: Preview failed: refreshing urn:pulumi:sandbox1::compute::aws:s3/bucket:Bucket::dev-file-storage-sse: 1 error occurred:
    	* error reading S3 Bucket (arn:aws:s3:::dev-file-storage-sse): InvalidARNError: invalid ARN
    caused by: invalid Amazon s3 ARN, unknown resource type, arn:aws:s3:::dev-file-storage-sse

The arn was copied from the console, so it's correct. Am I missing something obvious here? I can access the bucket without issues from the cli using the same user that pulumi is running with.

The ID in this case is just the bucket name. So your code should be

bucket_sse = aws.s3.Bucket.get(
    resource_name = "dev-file-storage-sse",
    id = "dev-file-storage-sse"
)

Oh for * sake! I just assumed "id" meant arn without checking! Thanks!
