Azure APIM - Advanced Policies - Control Flow - Unexpected Result

Question

Hi,

Hi have this expression evaluating as False with a json PATCH payload having {"accountEnabled" : false}
I really expect it to evaluate as True

What is wrong in this expression?

<when condition="@(context.Request.MatchedParameters.ContainsKey("accountEnabled") && (context.Request.Body.As<JObject>(true)["accountEnabled"].Value<bool>() == false))">

Note: The accountEnabled parameter is optional and I need to consider the possibility of it not being present in the request

TRACE:
choose (0.020 ms)
{
"message": "Expression was successfully evaluated.",
"expression": "context.Request.MatchedParameters.ContainsKey(\"accountEnabled\") && (context.Request.Body.As<JObject>(true)[\"accountEnabled\"].Value<bool>() == false)",
"value": false
}

Thanks,
JD

Hi @juni dev As mentioned in the previous thread the logic seems to be incorrect
<set-variable name="IsAccountDisabling" value="@(context.Request.Body.As<JObject>(true)["accountEnabled"].Value<bool>() == false)" /> This will set false if founds true as the value of accountEnabled.
You're comparing the value of accountEnabled (true) with false, that will return false and will set value false in the variable IsAccountDisabling That's why the condition never met:

<when condition="@(((bool)context.Variables["IsAccounPresent"]) && ((bool)context.Variables["IsAccountDisabling"]))"> where ((bool)context.Variables["IsAccountDisabling"]) will always return false.

please find the working policy which satisfies all the condition as per your requirement,

Hope this helps! Try and do let me know if you have any queries.
