Steps to reproduce

1. Create a sample API or modify an api to have for the backend the "Base URL" to use environmentalized fields (being present/provided within ../groups/group-X/instance-Y/envSettings.props) :

Example Base URL: http://${env.HOSTNAME}:${env.PORT.TRAFFIC} , where env.HOSTNAME=IP_APIGW_HOST
Resource path: /resourcepath

2. Virtualized the api and within the Frontend definition, for Outbound section -->Backend you should have

http://${env.HOSTNAME}:${env.PORT.TRAFFIC}/resourcepath

3. Attempt the export ./apim.sh -h apigw -port 8075 -u user -p pass -s api get "testapi" -o json
   Attached the relevant log output.

Remark: If I remove in the frontend definition for Outbound the port, "${env.PORT.TRAFFIC}", below error will not be present.

Could it be validation on the variable type (ex:integer as it's a port) but because it gets a string it raises this ?

Relevant log output
