Action Mods ReplaceValuesTransformation does not allow replacement of (Empty) values

[nikomaresco-csg]

in Spotfire Analyst, i'm able to create a new Replace Values transformation, leave the "Previous value" field blank, and enter any data type into the "Replace value with" field:

this allows me to replace (Empty) (or as it's shown here, (Empty value)) with a new value.

reproducing this with the Action Mods API is not possible. the following code fails with the error below:

const t = new ReplaceValuesTransformation(columnToReplace, null, 0);

Error: The argument newValue must have the same data type as the column, in this case String
Parameter name: newValue
    at createReplaceValuesTransform (C:\Users\...\.js:72:15) ->     const t = new ReplaceValuesTransformation(columnSignature, null, newValue);

this is repeatable with the following values: null, undefined, (Empty)

as a workaround, i was able to use the SN() function in a ReplaceColumnTransformation:

const t = new ReplaceColumnTransformation(columnToReplace, resultColumnName, "Real(SN([Value], '0'))";

if this workaround is the desired path, it should be mentioned in the documentation for ReplaceValuesTransformation. otherwise, there should be a way to indicate (Empty) in either the originalValue or newValue parameter.
