I am currently developing a kibana watcher alert and I am comparing two values to generate an email if the condition comes true. For that I calculated an average value and it comes with many decimal places (nearly 20). I found that it can be rounded into several decimal places from transform section. I have tried it and I got the results as well. Now I need to add those transformed results to the condition section. I have tried ctx.transform.payload to access the transformed payload but it results a null. So is there anything I am missing when accessing the transformed payload?
