NoRegionError: You must specify a region.

When trying to run senza create I am getting this error:

$ senza create --region eu-central-1 --force ../hello-flask/hello.yaml v56 ImageVersion=bus56 --stacktrace-visible
Generating Cloud Formation template.. EXCEPTION OCCURRED: You must specify a region.

Senza version 1.0.91

Does not happen with older versions of Senza though.

@jmcs @hjacobs Any ideas? Seems like related to some recent change.

[jmcs]

Can you check your aws configuration (in ~/.aws/config)?

[hjacobs]

@rafaelcaricio @jmcs it's a bug, the "region" needs to be passed through and the boto3 client for ACM needs to get the keyword arg (otherwise it falls back to global AWS config).

[hjacobs]

Damn, this ACM cert lookup changes already got us two bugs... 😞

[jmcs]

This probably also affects #275. I'll check it out.
