I tried to apply a absolute shift to a priceIndex curve:
PerturbationMapping mapping = PerturbationMapping.of(
and got an error in the report:
[Unknown curve type for PriceIndexValues, must be ‘NodalCurve’ but was ‘com.opengamma.strata.market.curve.ParallelShiftedCurve’
Any ideas on how to use perturbation for this curve?
