Info button on the right-hand side under Tickets > Views leads to an error

Hello there,

if I click on the i-icon a window opens on the right-hand side, but no content is displayed there, only an error message (see screenshots):



Of course, clicking on the "TRY AGAIN" button does nothing.

Regards,
Sven
