Real time data ingestion with Added columns

Hi, I have updated my data source for the druid and now I have 2 more columns added in my pipeline.

It’s in realtime, so I added both the field in the supervisor spec. The fields are visible now but the issue is that the values of that 2 added columns are null.

So now, every time I am pushing new data the value is null. Please can someone suggest a quick fix? Things going into production this weekend.

Please help
