Navigating the Extension to page 2 during upgrade causes error

During the upgrade form 10.4 to 11.3, there were more than 5 extensions to upgrade ... so I hit the second page navigation element at the bottom ... which caused:

org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate Velocity Macro for content [#if ("$!request.action" == '')
