Error when

Problem/Motivation

Drupal returns a WSOD when I try to view an org chart.

Steps to reproduce

Install the module org charts, create a chart, when finished click view. Drupal will crash and you'll see the WSOD.

The following error gets returned:
TypeError: Unsupported operand types: array + null in bootstrap_barrio_preprocess_menu_local_task() (line 556 of /var/www/html/web/themes/contrib/bootstrap_barrio/bootstrap_barrio.theme).

Proposed resolution

I created a patch to see if the locale is specified before generating the URL.
