Hi everyone, I am having trouble to capture entity like {PIN} pin is XyZx99 format.

It is alphanumerical value, starts with 4 letters, uppercase lowercase sensitive, and ends with 2 numbers. - I created values like 20 examples of values. - However, it doesn't capture the value for example kkkk99. It captures just "k" - Why would that happen? Is it because I need to input hundreds of example values in the entity configuration? I appreciate the help, thank you in advance.

Use a regex in a Javascript block instead:

last_utterance = last_utterance.trim()

const regex = /^[A-Za-z]{4}\d{2}$/
return regex.test(last_utterance) ? 'default' : 'error'

last_utterance = last_utterance.trim()

const regex = /^[A-Za-z]{4}\d{2}$/
return regex.test(last_utterance) ? 'default' : 'error'

Make sure to add the "error" path to the javascript step.

Hey W.Williams. Thanks for the help, I'll do it as you advised. Would that mean I shouldn't rely on any custom capture functionality in voiceflow and do it always by regrex?
