Azure.AI.AnomalyDetector 3.0.0-preview.7
Describe the bug
Trained a Multivariant model, now testing batch detection causing on this line
MultivariateDetectionResult response = client.GetMultivariateBatchDetectionResult(resultId);
the following exception:
Unhandled exception. System.InvalidOperationException: The requested operation requires an element of type 'Boolean', but the target element has type 'Null'.
at System.Text.Json.JsonElement.<GetBoolean>g__ThrowJsonElementWrongTypeException|17_0(JsonTokenType actualType)
at System.Text.Json.JsonElement.GetBoolean()

at Azure.AI.AnomalyDetector.MultivariateDetectionResult.FromResponse(Response response)
at Azure.AI.AnomalyDetector.AnomalyDetectorClient.GetMultivariateBatchDetectionResult(String resultId, CancellationToken cancellationToken)
...
While debugging this I found this result entry causing the issue since isAnomaly is not checked for null values in the code parsing it:
{
"timestamp": "2023-05-27T10:00:00Z",
"value": {
"isAnomaly": null,
"severity": null,
"score": null,
"interpretation": null
},
"errors": [
{
"code": "InsufficientHistoricalData",
"message": "Inference data is not enough. Please make sure the length of inference data is longer than one sliding window."
}
]
}
This may occur for other error message as well of course.
Expected behavior
To parse the result so the user can see the error message.
Actual behavior
Trained a Multivariant model, now testing batch detection causing on this line
MultivariateDetectionResult response = client.GetMultivariateBatchDetectionResult(resultId);
the following exception:
Unhandled exception. System.InvalidOperationException: The requested operation requires an element of type 'Boolean', but the target element has type 'Null'.

Reproduction Steps
Every time I trigger the batch detection and causing a result like the following the error above is happening:
{
"timestamp": "2023-05-27T10:00:00Z",
"value": {
"isAnomaly": null,
"severity": null,
"score": null,
"interpretation": null
},
"errors": [
{
"code": "InsufficientHistoricalData",
"message": "Inference data is not enough. Please make sure the length of inference data is longer than one sliding window."
}
]
}
