Issue with virtual host alias creation

Hello,

We are trying to to add an alias name for the default virtual host in SAP API management.

We have created an XML file, called: newvh.xml, with the following code

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<VirtualHost name="default">

<HostAliases>

<HostAlias><FQDN for the server where router and message processor are installed</HostAlias>

</HostAliases>

<Interfaces/>

<Port>9001</Port>

</VirtualHost>

This is the command that I run in order to update the alias:

curl -u <admin user email>:<password> -X PUT http://<management server address:8080/v1/organization/<org name>/environment/<env name>/virtualhosts/default -d’@./newvh.xml -H "Content-Type:application/xml"

This does not create the alias for the virtual host.

Please suggest a solution to get this fixed.

Thanks in advance.
