When I "PUT" an object using a pre-signed by localstack S3 URL, the localstack responds with "Content Length: 233" and `<PutObjectResponse>...</PutObjectResponse>` XML in the body.

        lifecycle = {

        }
    body = xmltodict.unparse(lifecycle)
    response._content = body
    response.status_code = 200
    return response
