Debug Output

https://gist.github.com/grodzik/485b73bd45c4c4ba7af0dd5e3c210cf6

Expected Behavior

api_gateway_domain_name should be created.

Actual Behavior

Below error accures:

* aws_api_gateway_domain_name.api: Error creating API Gateway Domain Name: BadRequestException: Trailing period should be omitted from domain name
    status code: 400, request id: 56a81101-2deb-11e9-aadc-11aff297d7ee

This is related to this line from the log. There's dot at the end. Although it's taken from same source, aws_route53_record doesn't have such issue (see line 53 of the log)

Running above code for the first time will show also error about non-existant domain for the certificate, which is not meaningful for this issue.
