SAM AppSync EnvironmentalVariables Property No Longer Available in Template

In the SAM version of AppSync, there is no property for EnvironmentalVariables like there was for the AWS::AppSync::GraphQLApi version.

Is there a way to provide AppSync with env variables (via the template) that are accessible in the JS resolvers?

Start by checking AWS SAM's AppSync template support and the AppSync documentation for environment variables accessible to JavaScript resolvers. Done means establishing whether the template can provide these variables, with the supported configuration or limitation clearly documented.
