zappa certify → AttributeError: 'NoneType' object has no attribute 'split'

[simsong]

I'm trying to set up zappa to use a private domain (aws-lambda.digitalcorpora.org). My zappa_settings.json file (below) specifies us-west-2 as the region, although I have put the certificate in both us-west-2 and in us-east-1 (since Zappa didn't like the cert in the us-west-2 region). zappa certify produces a stack trace.

zappa_settings.json:

Stack trace:

• Using Python 3.9 in a virtual environment

Expected Behavior

It should certify.

Actual Behavior

Stack trace.

Possible Fix

Right now the aws-lambda.digitalcorpora.org doesn't exist. I just made this a CNAME to ck9qrzfy5l.execute-api.us-west-2.amazonaws.com which is my service address for the lambda (which is working). The instructions at https://github.com/zappa/Zappa don't mention what I should do regarding DNS, BTW.

I created the DNS name and I'm getting the same error:

Curiously, even though I got an error, it works!
https://aws-lambda.digitalcorpora.org/

[simsong]

Update: if you are using AWS certificate manager but not using route53, this needs to be added to the json file:

        "route53_enabled" : false,

I added that, and now it works:

(venv) simsong@Simsons-MacBook-Pro digitalcorpora_app % zappa certify production                                                                                                         (bottle-dev)digitalcorpora_app

But another domain is giving this error:

However, even though I got the error, the system is now working.

[monkut]

I haven't used the certify or domain features.
It appears that we need better documentation, and clearer error messages/handling around this.

[simsong]

I will give you a PR with marginally improved documentation. I haven't figured out enough to understand why I'm sometimes getting errors and sometimes not getting errors. It's confusing.
