We have created a topic with some variables, which were marked as Input.
Since we didn't use them, we deleted those variables BUT, now, all the previous topics that redirected to this new one is throwing an error.
If we try to update those topics, by deleting and recreating the "Redirect to another topic" action, when we try to save the topic, we get: «Output variable to this topic changed. Save current topic. »
We cannot fix this and we are unable to publish new versions.
Any help or suggestion, that doesn't imply deleting all the existing topics and recreating everything from scratch?
