# Undefined array key “_user_id”

 * I’m getting a PHP warning:
 *     ```wp-block-code
       Undefined array key "_user_id" in /home/sites/1a/4/44afcb079c/staging_html/wp-content/plugins/simple-history/inc/class-wp-rest-events-controller.php on line 743'
       ```
   
 * Think this relates to new line added in Changeset [3171877](https://plugins.trac.wordpress.org/changeset/3171877)(
   release 5.0.2). Unlike all the other nearby accesses to $context[‘_user_id’],
   this new one does not include “?? null”.

 * Yeah I get them too. I need to check why my tests does not pick up these.
 * Sorry about it – will fix in next version!

 * This should be fixed in the just released version 5.0.4.
 * I have also added more tests to catch errors like this in the future 🤞.
