I have been failing repeatedly trying to create a Scripted Field that will break out nested JSON values as separate columns. (They are fields that indicate whether web traffic comes from a bot or spider) What am I missing?

The message looks like:

> message:  
> {  
> "spiderOrRobot": true,  
> "category": "ACTIVE\_SPIDER\_OR\_ROBOT",  
> "reason": "FAILED\_UA\_EXCLUDE",  
> "primaryImpact": "PAGE\_IMPRESSIONS"  
> }

My code to true and return the first JSON object was:

> ```
> > if (doc['message'].value != null) AND (doc['message.spiderOrRobot'].value != null) 
> > return doc['message.spiderOrRobot'].value; 
> > return '';
> 
> ```

This column is always present, but is often NULL. I've tried writing in exceptions to handle it, but I keep getting failed shards.

I tried to follow this post's lead, but no luck yet: [Scripted field conditionals failing (5 of 15 shards failed) - #3 by caub](https://discuss.elastic.co/t/scripted-field-conditionals-failing-5-of-15-shards-failed/147807/3)

haha, sorry, that was a forehead slapper - been switching between SQL too much this morning. Rewrote it multple ways. I sitll can't figure out why it isn't working.

Current iteration is:

> if (!doc['message'].empty && !doc['message.spiderOrRobot'].empty) {  
> return doc['message.spiderOrRobot'].value;  
> }
> 
> return '';
