Hello,

I'm trying to write some simple webscripts but when I try to use response templates to return some data
I get a template exception : 05200035 Error during processing of the template Expression "expression" is undefined on line …

For example:
test.post.json.js

function main(){
model.test = "Hello!";
}
main();
‍‍‍‍‍‍

test.post.json.ftl

{
"test" : "${test}"
}‍‍‍

test.post.desc.xml

<webscript>
  <shortname>test</shortname>
  <description>test</description>
  <url>/api/test/</url>
  <format default="json">argument</format>
  <authentication>user</authentication>
  <transaction allow="readwrite">required</transaction>
</webscript>
‍‍‍‍‍‍‍‍‍

Returns a TemplateException: 05200036 Error during processing of the template 'Expression test is undefined on line 2
in the log.

I'm calling my scripts using cURL,

curl -uadmin:admin -d  "" http://www.alfresco.test/alfresco/s/api/test/‍

You've specified the JavaScript controller as ".post.json.js" but this controller will only be used if the request content type is JSON.

i.e you need to add the ""Content-Type: application/json" header to your request.

In general, it's good practice in Freemarker templates to handle potentially missing variables, i.e.

${test!""}‍

Thanks,
Mike
