I'm trying to create REST-enabled data sources via https in APEX 20.2 and Database 18c XE. I have been able to generate a wallet and import the certificates for github, which work without issue in the Sample Rest Application. But when I try to use a certificate that uses a wildcard option I consistently get certificate errors. For example, the server certificate for github.com specifies www.github.com and github.com as valid names for the certificates. But a site such as darksky,net, their certificate is valid for *.darksky.net, *.forecast.io. And the darksky.net certificates.
I would really like to be able to test some datasources in XE before migrating to a full SE database 12.2. Is there any way to make this work?
