Javascript plugin seems broken

[clintongormley]

In 0.20.6, with the 1.3.0 JS plugin, I'm struggling to get anything to work. Perhaps I'm misunderstanding?

For instance, I'm trying to return a simple value as a script field. Any of the following requests throws a similar error (below):

curl -XGET 'http://127.0.0.1:9200/_all/_search?pretty=1'  -d '
{
   "script_fields" : {
      "foo" : {
         "script" : "return 5",
         "lang" : "js"
      }
   }
}
'
curl -XGET 'http://127.0.0.1:9200/_all/_search?pretty=1'  -d '
{
   "script_fields" : {
      "foo" : {
         "script" : "return 5.0",
         "lang" : "js"
      }
   }
}
'
curl -XGET 'http://127.0.0.1:9200/_all/_search?pretty=1'  -d '
{
   "script_fields" : {
      "foo" : {
         "script" : "return \u0027foo\u0027",
         "lang" : "js"
      }
   }
}
'
curl -XGET 'http://127.0.0.1:9200/_all/_search?pretty=1'  -d '
{
   "script_fields" : {
      "foo" : {
         "script" : "return \"foo\"",
         "lang" : "js"
      }
   }
}
'

Wrong version of JS plugin - closing

[clintongormley]

Actually, in 0.20.6 with JS plugin 1.2.0, i'm still getting parse errors. What's going on here?

[clintongormley]

Ah, it might be because i'm using return outside a function. Is there any chance of being able to see the parse error from the JS engine, rather than the Java stacktrace which is meaningless here?

[clintongormley]

It seems the error is there, just hidden in the flood of stack trace
