Externalizing the targer server as environment variable is not working

[#1]

Hello,

I have developed one API service in Apigee Edge called PostalCode for example. I used the "VehcileCode" proxy as a TargetServer for one more Proxy API.

If i configure postalCode service as a Target Server like below in a new Proxy API. This is working fine.

<HTTPTargetConnection>

<URL>http://manidemo-test.apigee.net/postalcode</URL> </HTTPTargetConnection>

I tried to externalize by configuring the PostalCode URL as a Environment variable in Apigee and

Named it as "Server_Postal_Code"

HOST : http://manidemo-test.apigee.net

PORT: 80

But its not working when i tried it like this:

<HTTPTargetConnection>

<LoadBalancer> <Server name="Server_Postal_Code"/>

</LoadBalancer>

<Path>/postalcode</Path>

</HTTPTargetConnection>

Getting error as : Trace below. It went into error flow on reaching the targetflow

Can someone help me ?
