Hello,

I am trying to use Rule engine. However, keep running into issues like below -
Exception while parsing expression client.filterRegion.regionId == inputClient.region.regionId - Enum type 'filterRegion' not found
Error while compiling rule RegionWithCountry: No property or field 'forceCountry' exists in type 'String', in ScopedParam: localFunction

Input workflow : -

[
  {
    "WorkflowName": "ClientRules",
    "GlobalParams": [
      {
        "Name": "SamePrimaryDomain",
        "Expression": "HelperUtils.CompareDomains(\"abc.domain.com\", \"abc.domain1.com\")"
      }
    ],
    "Rules": [
      {
        "RuleName": "SameDomain",
        "properties": {
          "RuleId": "1"
        },
        "SuccessEvent": "1",
        "ErrorMessage": "One or more adjust rules failed.",
        "ErrorType": "Error",
        "RuleExpressionType": "LambdaExpression",
        "Expression": "SamePrimaryDomain == true  "
      },
      {
        "RuleName": "Region",
        "properties": {
          "RuleId": "2"
        },
        "SuccessEvent": "2",
        "ErrorMessage": "One or more adjust rules failed.",
        "ErrorType": "Error",
        "RuleExpressionType": "LambdaExpression",
        "Expression": "client.filterRegion.regionId == inputClient.region.regionId"
      },
      {
        "RuleName": "RegionWithCountry",
        "LocalParams": [
          {
            "Name": "localFunction",
            "Expression": "client.forceCountry == true OR client.filterCountry == inputClient.locationcountry"
          }
        ],
        "properties": {
          "RuleId": "3"
        },
        "SuccessEvent": "3",
        "ErrorMessage": "One or more adjust rules failed.",
        "ErrorType": "Error",
        "RuleExpressionType": "LambdaExpression",
        "Expression": "RegionWithCountry == true"
      }
    ]
  }
]

While 2 rule parameter passed are -

var rp1 = new RuleParameter("client", requestWorkFlowFilter.GetInputRequstAndFilter());

{"forceCountry":true,"filterCountry":"Country 4","forceRegion":false,"forceDomain":false,"filterRegion":{"regionId":3,"regionName":"Region 3"},"client":{"hostName":"sampleClient.sample2.subdomain1.com","clientId":119,"clientName":"client"}}

-- This is item 2
inputclient -

{"client":{"hostName":"1.sample1.com","clientId":1,"clientName":"Client Name 1"},"location":{"country":"Country 1","countrycode":"1"},"region":{"regionId":1,"regionName":"Region Name 1"}}
