rasa data validate should warn when checkpoints create loops in stories

What problem are you trying to solve?

Users may accidentally create circular logic in stories using checkpoints. rasa data validate should flag this if it occurs.

What’s your suggested solution?

rasa data validate throws a warning mentioning which checkpoints caused the loop

Examples (if relevant)

For example, these stories:

version: “2.0”

stories:

• story: happy path 1 steps:

• intent: greet

• action: utter_greet

• checkpoint: cp_a

• story: happy path 2 steps:

• checkpoint: cp_a

• intent: mood_great

• action: utter_happy

• story: sad path 1a steps:

• checkpoint: cp_a

• intent: mood_unhappy

• action: utter_cheer_up

• action: utter_did_that_help

• checkpoint: cp_b

• story: sad path 1b steps:

• checkpoint: cp_b

• intent: affirm

• action: utter_happy

• checkpoint: cp_a

• story: sad path 1b steps:

• checkpoint: cp_b

• intent: deny

• action: utter_goodbye

creates a loop as shown in this diagram:

<span class="image-wrap" style=""></span>

Is anything blocking this from being implemented? (if relevant)
