How is it that the documented intent states in Lex are different from the actual available values?What is the difference between each of these states?

I am currently working on integrating aws Lex with lambda function written in TypeScript and I am facing a situation in which I need help .

Upon reading the aws documentation for LexV2 the following values are available for an intent state:

• Failed
• Fulfilled
• FulfillmentInProgress
• InProgress
• ReadyForFulfillment
• Waiting

However when I used the 'Waiting' value, The following error message showed up :

Invalid Lambda Response: Received invalid response from Lambda: Can not deserialize value of type Intent$IntentState from String "Waiting": value not one of declared Enum instance names: [ReadyForFulfillment, InProgress, Failed, Fulfilled]

Upon this I need help to:

1. Understand how is it possible to have values that are not recognized.
2. Understand the difference between each of these values (Note: not all of the accepted values are explained in the documentation)
