Textraxt + HITL request: HumanInTheLoop Mechanical Turk Job fails with error: Validation error

0

I was testing out the latency of Textract + HITL via Mechanical Turk. I created a flow defintion, a human loop config and then submitted a request on a document using:

humanLoopConfig = {
    'FlowDefinitionArn':flowDefinitionArn,
    'HumanLoopName':human_loop_unique_id,
    'DataAttributes': { 'ContentClassifiers': [ 'FreeOfPersonallyIdentifiableInformation' ]}
}

def analyze_document_with_a2i(document_name, bucket):
    response = textract.analyze_document(
        Document={'S3Object': {'Bucket': bucket, 'Name': document_name}},
        FeatureTypes=["TABLES", "FORMS"],
        HumanLoopConfig=humanLoopConfig
    )
    return response

While the response was fine, when I list all the human loops related to a flow definition, I get this response:

{'HumanLoopName': 'human-loop-id-here', 'HumanLoopStatus': 'Failed', 'CreationTime': datetime.datetime(2023, 6, 20, 8, 29, 35, 606000, tzinfo=tzlocal()), 'FailureReason': 'ValidationError', 'FlowDefinitionArn': 'flow-definition-arn-here'}

How do I figure out what the exact issue is?

Hi It may because of the flow definition configuration. Could you provide more details here so we can reproduce the issue?

  • Hi, sure! Since comments have a 600 character limit, I edited my question and added the function I used to create a flow definition. Hope this helps!

    But, if there was an issue with the flow definition configuration, why was it created successfully and active? Any idea?

  • Any updates here? Can anyone point to the right direction?
