FME(R) 2023.1.1.0 (20230928 - Build 23631 - WIN64)

I have a simple scripted parameter script in workbench to return the value of a deployment parameter and I’m wondering if there’s a bug in the interface. When I drag a user parameter onto the script canvas the code generated contains FME_MacroValues, eg.

FME_MacroValuesa'SomeUserParam']

If  I drag a deployment parameter, dpTest, onto the script canvas the code generated looks like

$(dpTest)

Here’s the script. The commented code fails; if I manually correct $(dpTest) to FME_MacroValuesa'dpTest'], it runs:

# Get the archive folder from deployment param
import fme

#arch = $(dpTest)
#return arch

return FME_MacroValuesM'dpTest']

Is this a bug? Thanks.
