Non-free fonts and MacTeX 20203003

[Giovanni Dore]

I installed MacTeX pretest version 20203003 and I tried to refresh the map of non-free fonts with
getnonfreefonts --refreshmap
but I get (once for every font) the error:
updmap: top config file /usr/local/texlive/2020/texmf-config/web2c/updmap.cfg has not been read. at /Library/TeX/texbin/updmap line 1495.
With the previous version of the pretest release I had no problem.
How can I solve this problem?

Regards

Giovanni
