Hi there! I have a Perspective page with authentication enabled, requiring users to log in. After a user logs in the button binding works fine but after sometime, `session.props.auth.user.userName` is occasionally not found in the default user source . Most of the time, the expression binding works fine, but sometimes this issue happens.

Note that `session.props.auth.user.userName` always has a value, but the default user source becomes empty when the issue occurs.

Error on button

What do you mean by this? What's your indication of this?

Hi @paul-griffith , it seems like on some rare instances , the users saved on this user source becomes empty and comes back again after a minute or two or reloading the perspective page. (This may be due to network issues, but i thought i share it to you in case there is a similar issue that you've encountered before)

I've never heard of that happening and I don't really see _how_ that could happen with an internal user source; the users and roles in the internal user source are in the same configuration database that holds everything else in your system, and it's stored as a file wherever the gateway is installed.

I would check your gateway logs for errors around the time these issues are happening, and also contact our [support department](https://support.inductiveautomation.com) officially.

Thanks for the clarification and suggestion! I'll check the gateway logs for any errors and reach out to the support department if needed. Appreciate your help!
