Portal Access rewrite process may crash when resource item configuration for the current request contains invalid value in Headers advanced option.


Rewrite crashes.


This can occur if the Headers options are empty, for example: tmsh modify apm resource portal-access <resource> items modify { <resource item> { headers { {} } } }


Fix the configuration: 1. find resource and resource item names of configuration blocks containing 'headers none' using the following command: tmsh list apm resource portal-access. 2. For each affected resource and its item, run the following command: tmsh modify apm resource portal-access <resource> items modify { <resource item> { headers none } }

Fix Information

APM Portal Access rewrite no longer crashes on invalid Custom Headers configuration.
