com.powsybl.cgmes.model.CgmesModelException: nominalVoltage not found for BaseVoltage

[chadhat]

Describe the current behavior

We are trying to run the convert-network functionality of itools. Our data is XML files from TYNDP 2020. We are trying to run the command as follows:

itools convert-network --input-file DE.xml --output-format XIIDM --output-file XIIDM\DE

However, we encounter the following error:

com.powsybl.cgmes.model.CgmesModelException: nominalVoltage not found for BaseVoltage 7891a026ba2c42098556665efd13ba94

There is no nominalVoltage in our TYNDP files. Any help or pointers are appreciated.
