Won't upload to existing bucket on deploy

[Sasha]

When deploying to an existing bucket, it errors out:

$ flask-zappa deploy production settings.json
Deploying production
Packaging project as zip....
An error occurred (BucketAlreadyOwnedByYou) when calling the CreateBucket operation: Your previous request to create the named bucket succeeded and you already own it.
Couldn't create bucket.

However when deploying to a new one that didn't exist before, it works:

It worked for me when the Bucket and zappa configuration point to the same region.

"BucketAlreadyOwnedByYou" error still exists unless the bucket is in the same region as zappa configuration points to.
