WSO2 APIUtil Error while creating axis configuration for tenant

Question

I'm using WSO2 API-Manager 3.0. When I browse to the DevPortal (before signing in) I can see the list of APIs.

But when I login (using my email as assigned by my organization's IAM team) I get a red pop-up message saying 'Error While Loading APIs':

The log file revels this message:

(plus another 200 lines of trace-back)

When I login to the Publisher the page loads with a spinning icon that says "Loading Settings" and stays there forever:

Again the log file reveals the same message as above.

Note: Other users in my organization are able to login and view the APIs just fine. But they are not using an email address to authenticate. I am the only using an email address to authenticate.

Another Note: Our organization uses an IAM server for authentication.

Any suggestions on what to try next to resolve this?

Answer 1

In WSO2 servers, the username john@tenant.com represents the user john in abc.com tenant. Therefore, you email domain has been identified as a tenant domain. Try the below format for your username. It should work.

john@gmail.com@tenant.com

If you don't have multiple tenants, use carbon.super as the tenant. So your username should go like this.

john@gmail.com@carbon.super
