How can happen that with a Lambda/API Gateway combination, if no explicit Cloud Front configuration has been done, in an error response header they mention CloudFront?

header: x-amzn-ErrorType: ForbiddenException
header: x-amz-apigw-id: P3mmbT_DREF8bg=
header: X-Cache: Error from cloudfront

Actual problem: with a disabled API key, API keeps responding "forbidden".

UPDATE. As it seems the problem is not related to the Edge API/CloudFront, as the problem with disabled key persists also on changing API type to regional.

UPDATE. I can now disable API key checking as suggested by @Harish i.e. it's not about disabling the API key itself but telling the API whether it's required or not.

What is yet open though is why if created by Zappa, there is no option to change this setting in the UI, because there are not single methods.

Besides setting API Key Required = false, I was missing something in API Gateway > Custom domain names:

The API Mapping had no stage selected. When I selected dev, the endpoint worked.

When you deploy an edge-optimized API, API Gateway sets up an Amazon CloudFront distribution and a DNS record to map the API domain name to the CloudFront distribution domain name. Requests for the API are then routed to API Gateway through the mapped CloudFront distribution.

Source: API Gateway documentation — Edge-optimized custom domain names.

To allow calls to a method of a resource in your API without API key, set its API Key Required setting to false:
