Golang SDK for Dynamodb : ReturnValuesOnConditionCheckFailure does not return the details about conditions when conditionchcekfailure occurs

I am using golang sdk https://pkg.go.dev/github.com/aws/aws-sdk-go@v1.45.26/ to debug conditional check errors and find information about why the failure occured in sIngle write operations, but I can only see the error Message_: "The conditional request failed". No other information regarding specific reason is provided when using the parameter ReturnValuesOnConditionCheckFailure: ALL_OLD in UpdateItemInput. In case of TransactWriteItems I can see specific reason of conditional check failure when using the same parameter. How can I obtain those details for single write operations as well? Reference: https://aws.amazon.com/about-aws/whats-new/2023/06/amazon-dynamodb-cost-failed-conditional-writes The syntax I am using:

input := &dynamodb.UpdateItemInput{
        TableName:                           aws.String("DummyTable"),
        Key:                                 keyAttr,
        ExpressionAttributeValues:           updateExpr.Values(),
        ExpressionAttributeNames:            updateExpr.Names(),
        ConditionExpression:                 updateExpr.Condition(),
        ReturnValues:                        aws.String(dynamodb.ReturnValueAllOld),
        UpdateExpression:                    updateExpr.Update(),
        ReturnValuesOnConditionCheckFailure: aws.String(dynamodb.ReturnValuesOnConditionCheckFailureAllOld),
}
output, err := dl.ddbI.UpdateItem(input)

The item should be within the error component usually in error.response.Item.

For example in python:

except botocore.exceptions.ClientError as error:
    if error.response["Error"]["Code"] == "ConditionalCheckFailedException":
        print("The conditional expression is not met")
        current_value = error.response.get("Item")

Note: if you're using DynamoDB Local this feature does not yet exist
