I'm currently using an event subscriber to latch onto an event from a module that creates and/or updates nodes. I'm programmatically setting the url alias based on a user inputted field by doing the following
$path = \Drupal::service('path.alias_storage')->save("/node/" . $node->id(), $url_alias, "en");
It works but when I open the node and attempt to edit it, I get the message
The alias is already in use
When I try to save it. Is there something I'm missing? Does a field on the actual node have to be edited as well?
I'm also using pathauto if that has any effect.
UPDATE: I just noticed that whenever that aliased is saved it generates 4 entries in the URL alias list.
