compareGroups: {test} needs a numeric column, but the column is not numeric.

Since

1.27.0

What happened

A specific test was forced - Welch's t-test or Mann-Whitney - and both compare numeric distributions. The column is not numeric, so the test cannot be run and the call returns null rather than coercing values into numbers.

The fix

Drop the test override and let the column family choose (a categorical column gets a chi-square), or compare a numeric column.
