Coldfusion: Nested Loop on api call Array & Struct

Question

My function calls the SendGrid API. It returns an Array + structure. I'm writing a function to return a CFQuery dataset.

Goal I want to pass a deserialized data object to my function and get a query dataset.

Here is my working code and the output:

<cfparam name="variables.ddata" default="#structnew()#">
<!--- API Call Code here --->
<cfset arr = DESerializeJSON(returnStruct.Filecontent) />
<cfdump var="#arr#">

My code:

 <cfset arrayit(arrobj= arr) >
 <cfdump var="#variables.ddata#" >
 <cffunction name="arrayit" access="public" returntype="void">
    <cfargument name="arrobj" type="array"  required="yes">
    <cfset var arr=arguments.arrobj />
    <cfloop from="1" to =   "#arrayLen(arr)#" index="i">
       <cfif isValid("string", arr[i])>
          <cfset StructInsert(variables.ddata, i, arr[i]) />
       </cfif>
       <cfif isstruct(arr[i])>
          <cfset structit(structobj = arr[i]) />
       </cfif>
    </cfloop>
</cffunction>

<cffunction name="structit" access="public" returntype="void" output="yes">
   <cfargument name="structobj" type="any" required="yes">
   <cfset  stru = arguments.structobj />
   <cfloop collection="#stru#" item="S"> 
       <cfif isValid("string", stru[S])>
          <cfset StructInsert( variables.ddata, S, stru[S]) />
       </cfif>
       <cfif isarray(stru[S])>
           <cfset arrayit(arrobj = stru[S]) >
       </cfif>
   </cfloop>
</cffunction>

Result:

When I add this line in my function

<cfif isstruct(stru[S])>
    <cfset variables.ddata   =  arrayit(arrobj = stru[S]) />
</cfif>

An error occurs:

Element type is undefined in a CFML structure referenced as part of an expression.
The error occurred on line 71.

I just did it! :) just wanted to share my project with you guys also hope it will help someone else also...

Request if you guys find anything you feel I can improve please share.

Special Thanks for response on my post. @Beginner & @Leigh
