Hi @kalpa916, What is exactly is your problem with the code above? What is the error? What doesn’t work?

when I am using regex for validating the slots it doesn’t validate

(e.g - intent: my_account_number examples: | - my a/c no is PR567 - PR569 is my a/c no - here is my PR890

  • regex: account_number examples: |
    • ^(PR)\d{3,9}
    • ^(pr)\d{3,9}

it doesn’t verify as per the regex and it also doesn’t show an error when wrong input is provided it goes to the next intent/action.
