I have written a watch program which uses percentile to calculate the 90th percentile of the aggregated data and when plotted against threshold,it should alert if its crossing the threshold. The percents parameter contains [90.0] in the array..But, am getting an error while executing the watch. error: Failed to execute watch input reason: "SearchPhaseExecutionExeception [all shards failed]; nested : [Parameter [percents] must be an array of doubles, type ArrayList provided instead]; nested : ParseException[Parameter[percents] must be an array of doubles, type ArrayList provided instead] ![image](https://us1.discourse-cdn.com/elastic/original/3X/6/1/61402d7583305b0216fd1cf62e5b8d7caddf078b.png) I have written 90.0 but when I view the watch code after creating the watch,it shows 90 in the array. Is this what the error is specifying saying it must be double, but found ArrayList..How should I overcome this..Please help me out..
