Backoffice zK error message when returning to browser window opened on backoffice.

[Former Member]

Hi Experts,

I have searched this issue in Experts and other places, but I could not find anything useful to solve my problem and I wonder if someone else has experienced it.

Once the user logs onto the Backoffice, if leaves the browser tab opened on the backoffice and he switches from the browser to another application or to a different browser tab, when he goes back to the backoffice window, a pop-up opens returning the error message "INTERNAL SERVER ERROR - Please try again later, or contact your system Administrator" and the following exception is traced in the log.

My Hybris version is 6.1.0.1. We made some customization to the Backoffice limited to specific user roles that we defined, but the problem occurs for every kind of user; even to users (ex: admin) who were not assigned to the user roles defined by us.

Has anyone any hints on this issue? Thank you,

Marco

Hi,

I suggest contacting our support. This is not a standard issue we are aware of.

Cheers, Wojtek

I have the same hybris version and the exact same issue. Is there any update on this topic?
