Iterate through JSON response in FTL

NicoB 

This is not working when I user .json()

.get() is Working

<#assign search_query = http.request.parameters.name.get("search_query","optimizely") />

<#assign response =  http.client.request("http://community/collection1/select?q=${search_query}&wt=json&indent=true").get() />
<#if response.hasError>
${response.error.message}
<#else>
${response.content}
</#if>

.json() is NOT Working

<#assign search_query = http.request.parameters.name.get("search_query","optimizely") />

<#assign response =  http.client.request("http://community/collection1/select?q=${search_query}&wt=json&indent=true").json() />
<#if response.hasError>
${response.error.message}
<#else>
${response.content}
</#if>

Error is as below:

{ "error":"
FreeMarker template error:
The following has evaluated to null or missing:
==> response.hasError  [in template "zendesksearchapiurl.ftl" at line 4, column 6]

Tip: If the failing expression is known to be legally null/missing, either specify a default value with myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthessis: (myOptionVar.foo)!myDefault, (myOptionVar.foo)??

The failing instruction (FTL stack trace):
