Using local transport within current tenant - wso2

Question

I want to deploy Carbon Application inside tenant on WSO2 ESB and use local transport between proxies. It looks to work fine when I use absolute URI with full domain e.g.:
local://services/t/my.domain.com/MyFirstProxy
And now I would like to pass message to another proxy in the same domain (tenant):
local://services/t/my.domain.com/MySecondProxy
I expect there should be posibility to refer second proxy either by relative path (without changing domain) e.g. local://services/MySecondProxy but if I try to use it this way ESB engine throws:

I need to deploy the same application in two separate domains independently and I don't want to use absolute paths as to be complicated in maintenance.
Is there a simple solution to use local transport without fixing domain name and use current domain by default?

Answer 1

In your scenario, you are using local transport within tenants in ESB. So u have to use absolute path when you are going to invoke tenant-based proxies.
You are getting an error, when you invoke proxy without domain as it going to assign it to carbon super.
FYI- If you want to make calls across tenants, you should use a non Local Transport even if they run from the same VM. [1] So it is not recommended to use local transport with tenants.
If you need you can use custom proxy path and refer documentation [2]
