I think the issue is that I have to use ?eval to convert it into ftl hash, but when I try using ?eval, it is still giving an error.

 

Can you suggest, where do I put ?eval so that I can iterate through the FTL hash using list

 

<#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>

Hi  Gursimrat 
I haven't tried it myself to be honest but looking at some internal documentation it seems that you're right, ?eval should parse a JSON string into a FTL hashmap.
You should be doing something like this:

<#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>
  <#assign theHash = ${response.content?eval}
  ${theHash.response.docs[0].summary}
</#if>

 Please let me know if this works.

 

Thanks,

Nico
