How to update a field which is of type array by using script in ElasticSearch?

I had a field named 'tags' in my documents, which is of type array, how can I do this:

If a tag is in the field 'tags', then do nothing; else add the tag to 'tags'.

Forgive me that I have no idea with groovy, but I've tried this:

curl -XPOST localhost:9200/file/company/13862/_update?pretty -d '{script:{inline:"ctx._source.tags.contains(tag) ? ctx.op=\"noop\" : ctx._source.tags += tag", params: {tag: 3}}}'

But it turns out the error:

"Failed to compile inline script [ctx._source.tags.contains(tag) ? ctx.op=\"noop\" : ctx._source.tags += tag] using lang [groovy]"

Try this 

{
  "script": {
    "inline": "if(ctx._source.tags.contains(tag)){ ctx.op = \"none\"} else{ ctx._source.tags += tag }",
    "params": {
      "tag": 3
    }
  }
}
