Passing request json through Azure function

[mtelang]

Hello @abbasc52

First, thank you for sharing this outstanding tool.

I have created an Azure function

namespace HttpRuleFunction
{
public static class HttpRuleFunction {
[FunctionName("HttpRuleFunction")]
public static async Task Run(
[HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");

        string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
        dynamic data = JsonConvert.DeserializeObject(requestBody);

        string discountOffered = new DemoApp.JSONDemo().Run(data);

        string responseMessage = string.IsNullOrEmpty(discountOffered)
            ? "Something went wrong. discountOffered string was empty."
            : $"{discountOffered}.";

        return new OkObjectResult(responseMessage);
    }
}

}

The http request body is

{"country" : "india",
"loyaltyFactor" : 5}

Also, I have simplified the Discount.json
[
{
"WorkflowName": "Discount",
"Rules": [
{
"RuleName": "GiveDiscount10",
"SuccessEvent": "10",
"ErrorMessage": "One or more adjust rules failed.",
"ErrorType": "Error",
"RuleExpressionType": "LambdaExpression",
"Expression": "propertyExpando.country == "india" AND propertyExpando.loyaltyFactor <= 2"
},
{
"RuleName": "GiveDiscount20",
"SuccessEvent": "20",
"ErrorMessage": "One or more adjust rules failed.",
"ErrorType": "Error",
"RuleExpressionType": "LambdaExpression",
"Expression": "propertyExpando.country == "india" AND propertyExpando.loyaltyFactor == 3"
},
{
"RuleName": "GiveDiscount25",
"SuccessEvent": "25",
"ErrorMessage": "One or more adjust rules failed.",
"ErrorType": "Error",
"RuleExpressionType": "LambdaExpression",
"Expression": "propertyExpando.country == "india" AND propertyExpando.loyaltyFactor == 5"
}
]
}
]

But in the ResultSet, I am getting exception

exceptionMessage "Exception while parsing expression propertyExpando.country == \"india\" AND propertyExpando.loyaltyFactor <= 2 - The binary operator LessThanOrEqual is not defined for the types 'System.Object' and 'System.Int32'."

If I run default program passing var basicInfo = "{"country": "india","loyaltyFactor": 5}"; it works fine.

Not sure why it is not accepting my JSON. Any help is appreciated

Thanks

I think that during the object journey through the function some serialization settings could be missed, a had the same issue with the nullable decimals and solved it in two ways: explicit convertation - propertyExpando.country == \"india\" AND Int32(propertyExpando.loyaltyFactor)<= 2 or custom ConvertUtiity with static method to convert objects/JTokens to Int32.
