Deprecated function: explode(): Padding null to parameter #2

[scottsawyer]

Deprecated function: explode(): Passing null to parameter #2 ($string) of type string is deprecated in Drupal\facets_hardcode\FacetsHardcodeSlugHelper::getSlugFromValue() (line 39 of modules/contrib/facets_hardcode/src/FacetsHardcodeSlugHelper.php).

The problem appears to stem from facets that haven't been configured in facets hardcode. I am adding a check that an entity is found before performing any more actions.
