Description

1.  Execute "select PART_DT,sum(PRICE) from KYLIN_SALES group by PART_DT"
2.  Expand "Query String"
3.  Then click "visualization" to show the chart
4.  If we choose the "-- choose metrics --" firstly, then we reopen Metrics drop-down box, then we can't see full metric options.

 

Then I analyse this operation will cause the error "Cannot read property 'index' of null" in visualization page, as follows:

message: "Cannot read property 'index' of null"
stack: "TypeError: Cannot read property 'index' of null?    at http://kylin_server:7070/kylin/js/scripts.min.20191108164741.js:55197:69?    at Object.forEach
