Hi @PetrG @mnchs12312321 @shellka thanks again for raising this issue. This is a bug and it has been reported.
This bug is triggered when IntentlessPolicy is used AND there is no e2e tests. If you want to continue using IntentlessPolicy there is a workaround: please create an e2e test, here is the link to docs how to do it: Evaluating Your Assistant (E2E Testing) | Rasa Documentation.
Please let me know if you still encounter the issue. Marina
