I think Rules is the best way here but I can't figure it out. I'm looking to automate creating the embed code from Eventbrite. The user can specify the Event ID and then I'd create the embed code in a new field. Easy enough I thought.
When it runs it logs the error
Drupal\rules\Exception\EvaluationException: Unable to get variable @node.node_route_context:node:field_eventbrite, it is not defined. in Drupal\rules\Engine\ExecutionState->getVariable() (line 103 of /home/site/wwwroot/modules/contrib/rules/src/Engine/ExecutionState.php).
If I try selecting it like
node:field_eventbrite it errors out before I can even save it.
