As far as I can see, It is the same problem encountered in issue #439

This problem have also been seen in eu-west-3, where there's no WAF service (this error will be triggered anywhere this service is unavailable (availability here)).

As @rifelpet suggested, a prerequisite of ALB creation would be a check through SDK function (documented here); Resolving endpoint first, and taking action accordingly, would be interesting. I am working w/ my team on a PR to develop this option.

@bigkraig : Regarding session information, I am digging around to easily retrieve region (configured through AWS profile/credentials). Do you have any suggestions in order to achieve it easily ?

@grockeek I've been using the AWS_REGION environment variable, AFAIK that is the only way to get it unless the app also accepts a parameter and overrides the client. aws-cli works the same way. Thanks for looking into this one!

I'm going to close this one since this is the same as #439.
