Hi @andres_pineiro, thank you for your response. I have tried various things and now seem to have found the problem. In fact, I have several slots with ‘influence_conversation: true’ and which are set via a custom action. But apparently only one of these slots has caused problems. Namely a categorical slot that had an ‘initial_value’ assigned to it. When I removed the ‘initial_value’ and defined it via a custom action, the rules worked again. Is this a bug or does it make sense? Are the rules trained with the initial_values of the slots?
