Name : /vpc/apigwvpcendpoint
Type : String
Value : https://!Sub(!Select [1, !Split [":", !Select [ 0, !GetAtt apiEndpoint.DnsEntries ]]])
CodePudding user response:
You can use array form of Sub:
Name: !Sub
- "https://${dns}"
- { dns: !Select [1, !Split [":", !Select [ 0, !GetAtt apiEndpoint.DnsEntries]]] }
