Skipping slot extraction because of invalid mapping

Rasa Open Source
1

I am trying to extract name from the user into the slot ‘name’.

I have added intent: “myname” in the NLU and the registered it in domain. I have also set the slot “name” with entity mapping to the entity “name”. But for some reason I keep getting this error:

Slot 'name' uses a 'from_entity' mapping for a non-existent entity 'name'. Skipping slot extraction because of invalid mapping.

I absolutely cannot figure out why this is happening. Is there any solution to do this or what am i doing wrong?

- intent: myname
  examples: |
    - my name is [John]{"entity":"name"}
    - name is [Doe]{"entity":"name"}
    - [John]{"entity":"name"} is my name
    - my identity is [Peter]{"entity":"name"}
    - [Steven]{"entity":"name"}
    - sure. here is my name [Tim]{"entity":"name"}

Below is all the places in domain where i have mentioned and registered “name”

slots:
  name:
    type: text
    influence_conversation: True
    mappings:
    - type: from_entity
      entity: name

I have other slots but all of them are custom types and name is the only entity extraction i wish to do.

entites:
  - name

intents:
  - myname

forms:
  user_details_form:
    required_slots:
      - name

What is going on? Have I missed something?

Weird… Can you send your domain file?

Also please share the output of the rasa --version command.

i figured it out, it was a spelling mistake in “entities”

The same warning happened to me, just like you it was due to a spelling error when writing entities, your post helped me solve my problem. Thanks ! Cheers!
