create variable can't use the data source as 'MODEL_SCORE'

in the boto3 document, the dataSource can be 'MODEL_SCORE' https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/frauddetector.html#FraudDetector.Client.create_variable

But, your notebook will be failed with the following message:

ValidationException: An error occurred (ValidationException) when calling the CreateVariable operation: 1 validation error detected: Value 'MODEL_SCORE' at 'source' failed to satisfy constraint: Member must satisfy enum value set: [EXTERNAL_MODEL_SCORE, EVENT]

boto3 version is 1.16.10

create variable can't use the data source as 'MODEL_SCORE'

Sorry for my late reply...

Good callout, you are right that the model score variable will be automatically created by the service, so I commented that part out in the updated end-to-end notebook

timestamp is compliant with ISO 8601 format

error message: ValidationException: An error occurred (ValidationException) when calling the GetEventPrediction operation: Event Timestamp is not valid. Please verify that event timestamp is compliant with ISO 8601 format.

When call function "get_event_prediction"

My code is

timestampStr=datetime.utcnow().replace(microsecond=0).isoformat()

timestampStr is like this string '2020-11-04T09:39:29'

timestamp is compliant with ISO 8601 format

Sorry for my late replay, yes if you are using ISO 8601 standard, it needs to be in that specific format. It is documented in AFD's user guide: https://docs.aws.amazon.com/frauddetector/latest/ug/online-fraud-insights.html#preparing-training-data
