[BUG] Deserializing Issue w/SelectionMark FR 3.1.0-beta.4

Describe the bug In cases where the model expects to see a selectionMark (all custom models trained have one), an “Unknown SelectionMarkState value.” error is returned. This specific case was on a radio box selection, not a checkbox.

Expected behavior Return a null value if the selectionMark cannot be found due to poor image quality or handwritten form hides the mark

Actual behavior (include Exception or Stack Trace) { “ClassName”: “System.ArgumentOutOfRangeException”, “Message”: “Unknown SelectionMarkState value.”, “Data”: null, “InnerException”: null, “HelpURL”: null, “StackTraceString”: " at Azure.AI.FormRecognizer.Models.SelectionMarkStateExtensions.ToSelectionMarkState(String value)\r\n at Azure.AI.FormRecognizer.Models.FieldValue_internal…ctor(FieldValueType type, String valueString, Nullable1 valueDate, Nullable1 valueTime, String valuePhoneNumber, Nullable1 valueNumber, Nullable1 valueInteger, IReadOnlyList1 valueArray, IReadOnlyDictionary2 valueObject, Nullable1 valueSelectionMark, Nullable1 valueGender, String valueCountry, String text, IReadOnlyList1 boundingBox, Nullable1 confidence, IReadOnlyList1 elements, Nullable1 page)\r\n at Azure.AI.FormRecognizer.Models.FieldValue_internal.DeserializeFieldValue_internal(JsonElement element)\r\n at Azure.AI.FormRecognizer.Models.DocumentResult.DeserializeDocumentResult(JsonElement element)\r\n at Azure.AI.FormRecognizer.Models.AnalyzeResult.DeserializeAnalyzeResult(JsonElement element)\r\n at Azure.AI.FormRecognizer.Models.AnalyzeOperationResult.DeserializeAnalyzeOperationResult(JsonElement element)\r\n at Azure.AI.FormRecognizer.FormRecognizerRestClient.GetAnalyzeFormResultAsync(Guid modelId, Guid resultId, CancellationToken cancellationToken)\r\n at Azure.AI.FormRecognizer.Models.RecognizeCustomFormsOperation.UpdateStatusAsync(Boolean async, CancellationToken cancellationToken)\r\n at Azure.AI.FormRecognizer.Models.RecognizeCustomFormsOperation.UpdateStatusAsync(CancellationToken cancellationToken)\r\n at Azure.Core.OperationHelpers.DefaultWaitForCompletionAsync[TResult](Operation`1 operation, TimeSpan pollingInterval, CancellationToken cancellationToken)\r\n at FormRecognizerFunctions.MedicalCertificate.Run(HttpRequest req, ILogger log) in C:\Users\T002845\source\repos\FormRecognizerFunctions\MedicalCertificate.cs:line 46", “RemoteStackTraceString”: null, “RemoteStackIndex”: 0, “ExceptionMethod”: null, “HResult”: -2146233086, “Source”: “Azure.AI.FormRecognizer”, “WatsonBuckets”: null, “ParamName”: “value”, “ActualValue”: “O” }

To Reproduce Steps to reproduce the behavior (include a code snippet, screenshot, or any additional information that might help us reproduce the issue)

1. Train a custom model that uses a radio button checkbox and have all trained models where the selection can be found
2. Define custom model tag as a selectionMark
3. Analyze an image using the model where the value cannot be found.
4. In most cases it returns null as expected, however I have 2 documents that consistently toss the error. I am unable to provide those documents due to restrictions. I have tried recreating some mock documents that would cause the same error to occur but unfortunately haven’t been able to.

@RJWerning I am going to close the issue as you are unblocked. As for the past errors, looks like the service was returning new values that the SDK was not aware of and therefore the exception. This has been fixed in the new upcoming version.

Thanks!

Yes, I’m unblocked.
