Metric Undefined After Transformation drops RefID #364

Open lawhoisun opened 2 years ago

lawhoisun commented 2 years ago

Hi, I've come across several raised issues regarding the rules metric showing up as "Undefined" and experienced it myself using several different datasources. Not too sure if these transformation debug captures can help you guys fix this.

When I put in a dummy transformation, the resultant output is as expected with the Metric selectable. image

However, for certain transformations, like: Rows to Fields, the RefId is dropped. This causes the problem of Metric showing: Undefined image

Cheers Kelvin

The same issue is happening not matter what datasource is selected; When we use labels to fields transformation then refid is being dropped in transformation output and flowcharting plugin doesn't work; This is an important feature which is missing
