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)
