Expression Issue

[armenasadyan]

Hi,
For some reasons I need to use version 3.1.0.0.

{
"WorkflowName": "inputWorkflow",
"Rules": [
{
"RuleName": "GiveDiscount10Percent",
"SuccessEvent": "10",
"ErrorMessage": "One or more adjust rules failed.",
"ErrorType": "Error",
"RuleExpressionType": "LambdaExpression",
"Expression": "input1.country == "usa""
}
]
}

When I execute rule, I have exception message: Exception while parsing expression input1.country == "usa" - Method not found: 'System.Func2<!!0,!!1> FastExpressionCompiler.ExpressionCompiler.CompileFast(System.Linq.Expressions.Expression1<System.Func`2<!!0,!!1>>, Boolean)'.

Please advise.

Thank you.

It looks like dependency issue. It says it is unable to find FastExpressionCompiler.ExpressionCompiler.CompileFast method (at runtime). You might want to check if you have a different version of FastExpressionCompiler in your code and you might be able to fix it by adding the correct version of FastExpressionCompiler (>= 2.0.0) in your dependency.

Let me know if this helps.

Thank you Abbas, that works.
