Fieldmap not correctly imported

[aciarma]

I tried to use a geometry including a magnetic field map but ddsim/dd4hep2root prompt an error during the import. It happens both for fields of types FieldXYZ and FieldsBrBz. This happens also with current releases of ILD which use field maps. The file is correctly read, as the parameters of the map are displayed, but the field type is unknown.

Example:

source /cvmfs/fcc.cern.ch/sw/latest/setup.sh"
cd k4geo/ILD/compact/ILD_l5_v04
dd4hep2root -c ILD_s5_v04.xml -o ILD_s5_v04.root

Output:

Cannot reproduce

source /cvmfs/fcc.cern.ch/sw/latest/setup.sh
dd4hep2root

Gives

bash: dd4hep2root: command not found

maybe is this file? https://github.com/key4hep/k4geo/blob/main/utils/dd4hep2root.py

yes sorry, I forgot it was not automatically in the environment. But it gives the same error also with ddsim
