Region error despite specifying region

[M-Pixel]

In the S3 online interface, my region is listed as "Oregon", which is us-west-2

My config is

{
  action: 'write',
  bucket: 'actualbucketname',
  region: 'us-west-2'
}

yet I still get the error TypeError: Error: PermanentRedirect: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.
