Hey,

Is it possible to use the values you get from transform in the action log message?  
In my transform, I calculate the derivative and want to display it in my log/slack message.

If you are using a transform, then you can **only** use the values, that the transform returns, and you do not have access to the original payload.

Can you explain where the problem is or show the `transform` snippet?

Thanks!

Hey, I'm trying to access the transform's payload from actions in order to see it in logs.

Here's an example:

"transform": {  
"script": {  
"source": "ctx.payload.transform = []; def document = []; for (int j=0;j\<ctx.payload.hits.hits;j++){ document = ['test': ctx.payload.hits.hits[j].\_source.message]; ctx.payload.transform.add(document); } return ctx.payload.transform;",  
"lang": "painless"  
}  
},  
"actions": {  
"my-logging-action": {  
"logging": {  
"level": "info",  
"text": "{{ctx.payload.transform}}"  
}  
}  
}

the payload is **replaced** with the data you return in the `transform`. try logging `{{ctx.payload}}` and you will see your list.
