Hello Guru,

I've reviewed the requirements for the `agentVersion` parameter. It appears that it must be a fixed length of 5 characters and match the pattern `^DRAFT$`. This means the only acceptable value for `agentVersion` is "DRAFT". Using any other value, such as "v1", will not meet the validation requirements and will result in a Validation Exception.

> 💡 Please ensure that you are passing the correct value "DRAFT" for the `agentVersion` parameter, as this is the only value allowed based on the constraints provided.
