1.15 to 1.16 migration failed


I try to upgrade my actual foreman from 1.15 to 1.17. (Centos 7.4, 7.5)
I use the doc Foreman :: Manual

But when i start foreman-installer to upgrade i have the error message bellow
Parameter foreman-compute-vmware-version invalid: nil is not a valid string

I try to uninstall / reinstall the vmware package or disable without success to continue my upgrade

Any help on that ?

Thanks a lot.

resolv by using foreman-installer -i
and reset for the plugin vompute-vmware all value to default value
