Amazom Lex Bot Not working properly all time

Hi, the reason that Lex is aksing for it again and again, is because of the slot retries being set on the slot. Default is 3 retries. Now, as for not taking the slot value, its because Lex is not able to resolve the user-input to the associated slot. You can improve resolution by adding slot type values to your slot type and this will be used as training data. Ref: https://docs.aws.amazon.com/lexv2/latest/dg/custom-slot-types.html

Depending on your use-case if you just wish to capture the user-input as is as the slot value you can use the built-in slot type AMAZON.FreeFormInput: https://docs.aws.amazon.com/lexv2/latest/dg/built-in-slot-free-form.html Another one that allows to capture alphanumeric values but allows you to define your regex for the user-input is: https://docs.aws.amazon.com/lexv2/latest/dg/built-in-slot-alphanumeric.html
